This is the reason phosphorous is commonly a limiting nutrient. Hydroxyapatite (HAP), a crystalline form of calcium phosphate with a chemical formula of Ca10(PO4)6(OH)2, has been mooted as an alternative enrichment material for phosphopeptides based on the strong interaction between phosphate and calcium ions. Strong covalent bonds form between the phosphate group and two 5-carbon … The first method of synthesis of dendrimers possessing phosphate groups as branching points was reported by Damha et al. The 2' hydroxyl group is right next to the electrophilic phosphorus atom, poised in a good position to make a nucleophilic attack, breaking the RNA chain and forming a cyclic phosphate diester intermediate (see figure below). Each phospholipid molecule within the bilayer has a phosphate group at the head of the molecule. Four milliliters of modified universal buffer (MUB) of pH 6.5 was added, followed by 1 mL 0.05 M p-nitrophenyl phosphate. DNA and RNA serve different functions. They are made up of nucleotides, which in turn are made up of a nitrogenous base, a 5-carbon sugar, and a phosphate group. Due to their phosphate groups, nucleic acids are negatively charged at all but the most acidic of pH conditions. Mamone et al.75 prepared a HAP-packed microcolumn to selectively enrich phosphopeptide from a tryptic digest of standard phosphorylated protein mixture. RNA is a kind of nucleic acid, which performs an essential function in the flow of information from the DNA to the proteins. Which of the following is a use of a phosphate group within a cell? A phosphate group attached to the 5′-end permits ligation of two nucleotides, i.e., the covalent binding of a 5′-phosphate to the 3′-hydroxyl group of another nucleotide, to form a phosphodiester bond. The spectrum of a solid phospholipid may show fine structure at low temperatures, which disappears on heating. The sugar is a 2′-deoxy-d-ribose in DNA and a d-ribose in RNA. However, plants with reduced levels of SSII showed a 50% reduction in starch phosphate.134 Potato plants showing reduced expression of SSIII, however, displayed a 70% increase in starch phosphate.135 This suggests that the SSII isoform of SS plays an important role in the incorporation of phosphorylated residues into the growing α-(1 → 4)-glucan chain. Conversely, the separation and analysis of nucleic acids can be tuned by selection of an appropriate matrix and composition (Table 1). where q is the charge on a particle of radius R and η is the solvent viscosity. The sugars in the backbone. The “backbone” of a nucleic acid molecule is formed by the repeating sequence of pentose and phosphate groups, and this is the same in all molecules. The sugar in DNA is 2-deoxyribose, which is a pentose (five- carbon) sugar. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V.

Vassilios Roussis, in, Costa et al., 2017; Banskota et al., 2014; Yuan, 2007; Bhaskar et al., 2004; Le Tutour et al., 1998, These are polymerized from nucleotides (the monomers) each constituted from a sugar, a. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.The two strands run in opposite directions, one going in a 3' to 5' direction and the other going in a 5' to 3' direction. in 2000.14 This series of thiophosphate dendrimers was obtained first by the reaction of a triol with a phosphoramidite possessing acetate groups, followed by oxidation with elemental sulfur. The process can be seen in the following diagram. To understand the complete structure of a nucleotide, let's try to understand the structure of these groups one by one. Each segment of RNA or DNA is linked to the next by a phosphate. These macromolecules consist of a large number of linked nucleotides, each composed of a sugar, a phosphate, and a base. In this case the so-called Ferguson plot gives the relationship between the gel concentration and the electrophoretic mobility (sieving effect). The order of the nitrogenous bases – thymine(T), guanine(G), cytosine(C), and adenine(A), is crucial in determining the genetic code. Typically, a signal transduction pathway starts by a chemical arriving at an integral membrane protein. That is, the DNA is thought to reptate through the pores of the gel in a wriggling, snake-like manner. DNA and RNA molecules are polymers. A phosphate group functions as part of energy-storing molecules, has an important role in the regulation of cellular metabolism, and is even a constituent of DNA and RNA. A free phosphate group within the cytoplasm can also act as a buffer, attaching to strong acids or bases, and decreasing their effect on environment as a whole. The ester carbonyl frequency and bands between 670 and 1050 cm−1 may shift due to the variations in the crystal structure arising from different polymorphs. Various dendrimers based on thymidine and adenosine building blocks were synthesized by repetition of chain elongation and branching steps.12 The dendrimers were isolated after cleavage from the solid phase (Figure 6). Thus, separation of very high (>60 kbp) molecular weight DNA requires other techniques, such as pulsed-field gradient electrophoresis. These series of phosphodiester bonds become the sugar-phosphate backbone of the molecule. This ADP molecule can accept another phosphate group, and become adenosine triphosphate. The sugar phosphate backbone is an important stuctural component of DNA. Successive nucleotides of DNA and RNA are joined together by phosphodiester linkages involv­ing the 5′-phosphate group of one nucleotide unit and the 3′-hvdroxyl group of the neighboring unit (Figure 7-5). The sides connecting all the molecules are where the phosphate backbones are. Signal transduction is the process of transmitting a chemical signal through the cellular membrane. RNA is involved in protein synthesis and its regulation. These proteins cross the cellular membrane. The nucleotides for DNA go by the name of Deoxyribo-nucleotides. RNA nucleotides, unlike the deoxynucleotides of DNA, have a hydroxyl group at the neighboring 2' carbon. In DNA and RNA, nucleotides are covalently linked by the phosphate group; the negative charge of the phosphate group at neutral pH is essential for stabilizing nucleotides against hydrolysis and for retaining them within a lipid membrane. For the expression of the gene, information has to be conducted via RNA. Figure 6. A phosphate group functions as part of energy-storing molecules, has an important role in the regulation of cellular metabolism, and is even a constituent of DNA and RNA. RNA sometimes forms a secondary double helix structure, but only intermittently. How can a molecule (such as ATP) store energy? D. double helix. Unfortunately for organisms, it is primarily based on a source of phosphorous atoms. Hartwell, L. H., Hood, L., Goldberg, M. L., Reynolds, A. E., & Silver, L. M. (2011). The phosphate group comes from phosphoric acid (H3PO4), which has lost 2 hydrogen atoms. The contents were mixed properly and filtered. 1. This makes the addition of this molecule to a larger molecule easier. In DNA and RNA, nucleotides are covalently linked by the phosphate group; the negative charge of the phosphate group at neutral pH is essential for stabilizing nucleotides against … These labels can be used for either capture or detection. When nucleotides are not attached to other nucleotides to form part of DNA or RNA, two more phosphate groups are attached. The bonds between atoms are rapidly moving electrons, A small explosion occurs when bonds break, Each phosphate group is an important part of the sugar-phosphate backbone, Phosphate is used to cap certain DNA sequences. Therefore, excellent selectivity and sensitivity for detection of multiphosphorylated peptides were achieved. RNA nucleotides, unlike the deoxynucleotides of DNA, have a hydroxyl group at the neighboring 2' carbon. The flasks were swirled, stoppered, and placed in an incubator at 37°C for 1 h. At the completion of incubation, the flasks were opened and swirled to mix the contents. DNA (and RNA) are polymers made up of five-carbon sugars, organic nitrogen-containing bases, and phosphate groups. This sugar molecule is linked to the phosphate group. The infrared spectra of solid phospholipids vary due to the occurrence of polymorphism. The nucleotides for DNA go by the name of Deoxyribo-nucleotides. AMP, ADP and ATP for adenosine 5'-monophosphate, adenosine 5'-diphosphate and adenosine 5'-triphosphate, respectively). All the phosphodiester linkages in DNA and RNA strands have the same orientation along the chain (Fig. 2. Each nucleotide is made up of a pentose sugar, a nitrogenous base, and a phosphate group. Phospholipids, fundamental building blocks of cell membranes consisting of a polar or charged head group (phosphate) and one or two nonpolar fatty acid tails, connected via a glycerol linkage, possess antioxidant, antiinflammatory, and antiproliferative activities (Costa et al., 2017; Banskota et al., 2014; Yuan, 2007; Bhaskar et al., 2004; Le Tutour et al., 1998). The nucleic acids DNA and RNA are made from chains of nucleotides. The concentration of p-nitrophenol hydrolyzed by the sample was calculated from the standard curve. Both DNA and RNA contain a sugar phosphate group as the backbone to their structure. A phosphate group. DNA and RNA both have a sugar-phosphate backbone and nitrogenous bases. The end product extraction was done by adding 1 mL of 0.5 M CaCl2 and 4 mL of 0.5 M NaOH. Examine the view of DNA labeled "phosphate group". As you can see, the single nucleotide is made up of three important groups: The phosphate, sugar, nitrogenous base, and these groups are attached to one another by bonds, which we will discuss later. In DNA, the sugar molecule has one oxygen atom less, which is why it’s called deoxyribose (C5H10O4). The second step of this method was the deprotection of the siloxane. Further, when coupled with adenosine, the phosphate group can bind a series of other phosphates. RNA is involved in protein synthesis and its regulation. Dotaniya, ... K.L. A phosphate group consists of a phosphorous atom bound to four oxygen atoms. Because of the sharing of electrons within the structure, the molecule can approach another at any angle and have a good chance of being in the proper configuration to react. Each nucleotide contains a phosphate, a 5-carbon sugar molecule and a nitrogenous base. The key difference between DNA and RNA structure is that the DNA structure is a double helix composed of two complementary strands while RNA structure is single-stranded.. Nucleic acids are macromolecules or biopolymers. Labeled primers can be used for both capture and detection. This helps cells maintain an regular and consistent pH, and allows cellular processes to evolve. Summary of Differences Between DNA and RNA . Figure 8. However, double-strand formation and counterion condensation serve to decrease the flexibility of the nucleic acid, and as a result the reptating nucleic acid behaves more as a stiffly jointed rod in its transport through a sieving gel. Nucleic acids are long biological macromolecules that consist of smaller molecules called nucleotides. The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the ring. The sugar molecule in RNA is a ribose sugar, which is a 5-carbon sugar molecule (C5H10O5). Nitrogen Bases. Genes are formed by the order of the nitrogenous bases present in the DNA which is crucial for protein synthesis. Thus, under constant applied electric field, the mobility is determined primarily by the pore size of the gel matrix. Nucleotides consist of three components: a five-carbon sugar (either ribose or deoxyribose), a nitrogenous base attached to the sugar’s 1'-carbon, and a phosphate group attached to the sugar’s 5'-carbon. In fact, because each base carries a phosphate moiety, the charge-to-mass ratio of nucleic acids is essentially independent of size and form (e.g., single stranded versus double stranded, linear versus plasmid). All Right Reserved. They are extremely important in the function of DNA. Notice a phosphate group is a central phosphorous atom covalently bonded to 4 oxygen atoms. On hydrolysis by either of the enzymes, it yields p-nitrophenol, the color of which is read spectrophotometrically. The p-nitrophenyl phosphate acts as a substrate for both acid and alkaline phosphatases. The unit of structure is therefore a nucleotide, composed of a nucleoside and a phosphate group. 3)the phosphate groupe. The hydrophobic tails are collected together, forming a semi-permeable membrane which separates the contents of the cell from the outside. The 5-carbon sugar and the phosphate group of each nucleotide attaches to form the backbone of DNA and RNA. The key difference between DNA and RNA structure is that the DNA structure is a double helix composed of two complementary strands while RNA structure is single-stranded.. Nucleic acids are macromolecules or biopolymers. Condensed (e.g., supercoiled) DNA behaves most closely to a spherical particle, whereas linear DNA exhibits mobility that reflects its polymeric nature. The backbone of DNA is based on a repeated pattern of a sugar group and a phosphate group. nucleotide. The color intensity was read at 440 nm using a spectrophotometer. DNA and RNA both have a sugar-phosphate backbone and nitrogenous bases. Each nucleotide is made up of three components: 1. a nitrogenous base 2. a pentose (five-carbon) sugar 3. a phosphate group Each nitrogenous base in a nucleotide is attached to a sugar molecule, which is attached to one or more phosphate groups. Each free nucleotide has two additional phosphate groups, which will be used in the reaction binding it to the DNA chain. The diagram at the right could be a short section of RNA, or a single strand of DNA. When the protein is activated by the chemical, it changes shape slightly, activating another enzyme inside of the cell membrane. In DNA and RNA, the phosphodiester bond is the linkage between the 3' carbon atom of one sugar molecule and the 5' carbon atom of another, deoxyribose in DNA and ribose in RNA. The phosphate group of the nucleotides are used to link each nucleotide (in both DNA and RNA) to the nucleotides that are next to them. The 2' hydroxyl group is right next to the electrophilic phosphorus atom, poised in a good position to make a nucleophilic attack, breaking the RNA chain and forming a cyclic phosphate diester intermediate (see figure below). DNA is used for storage of genetic information. It is worth noting that the PA-coated diamond nanoparticles have an exceptional bias toward multiply-phosphorylated peptides, due to the strong arginine-phosphate interaction. At some temperature below the melting point of the lipid, the fine structure disappears completely due to movement of the acyl chain. The phosphate group of phospholipids shows a strong PO stretching band at 1350–1250 cm−l, which is sometimes a doublet and may be shifted to lower frequencies with an increase in intensity. In its free state, a phosphate group is centered around the phosphate atom, with 4 oxygens surrounding it. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. The bases pair preferentially: A with T (or U), via 2 hydrogen bonds, and C with G via 3 hydrogen bonds (complementary base pairing, CBP). The bases found in both DNA and RNA are Adenine, Guanine and Cytosine. Nucleotides this is a group of molecules that when put together, form the building blocks of DNA or RNA that made of a phosphate group, the bases adenine, cytosine, guanine, and thymine, and a pentose sugar, in RNA the thymine base being change by uracil. Nucleotides is a structural unit. sugar-phosphate backbone The alternating chain of sugar and phosphate to which the DNA and RNA nitrogenous bases are attached (formed by phosphodiester bonds) Uracil differs from thymine in that it lacks a methyl group. J.M. And the nucleotides for RNA go by the name of Ribo-nucleotides. one, two or three phosphate groups; the sugar can be ribose (in RNA) or deoxy-ribose (in DNA) and the base can be a purine or a pyrimidine base. Another major function of a phosphate group within biological systems is as part of the cellular messenger, cyclic adenosine monophosphate. By optimizing a phosphate buffer gradient for stepwise peptide elution, mono-, di-, tri-, and multiphosphorylated peptides were separated successfully. Nuclic acids are polymers of nucleoside mono phosphates linked togetherby 3' - 5' phospho diester linkages----RNA like DNA but it has . A)guanine B)adenine C)uracil When you add another phosphate group, you get adenosine diphosphate (ADP). As a result, nucleic acids migrate readily in an electric field from the cathodic to anodic (negatively to positively charged) ends of the apparatus. This lack of an oxygen atom also plays a role in the helical structure of DNA. During polymerization RNA spontaneously folds to a definite compact structure according to a least-action principle (see Section 8.2.11), in which base-pairing via hydrogen bonding is equivalent to the potential energy, and loop and hairpin formation is equivalent to the kinetic energy. The sugar is the 3' end, and the phosphate is the 5' end of each nucleotide in the DNA. Solid phases also can be coated with monoclonal or polyclonal antibodies. Opening remark DNA was isolated for the first time in 1869 by Frederick Miescher. MAYAKASHYAP5101 MAYAKASHYAP5101 Thymine is found in DNA not In RNA kya help chiye bro ok bro kal pakka kal New … The phosphate groups in the polar backbone have a pK near 0 and are completely ionized and negatively charged at pH 7; thus DNA is an acid. Antisense inhibition of SBE in potato caused elevated phosphate levels in the tuber starch.136, C.M. Using an automated DNA synthesizer for chain extension in the solid phase, adenosine phosphoramidate was added for creating the branching points by coupling two adjacent polymer-bound nucleotide chains. WagesJr, in Encyclopedia of Analytical Science (Second Edition), 2005. Each nucleotide is made of 3 parts: A pentose sugar. Phosphate group (circle) Nitrogenous base (rectangle) Both the phosphate group and nitrogenous base are attached to the central pentose sugar. Most frequently, this is accomplished by electrophoresis through a sieving medium, i.e., a gel, through which small molecules will pass more easily and larger ones will pass more slowly, due to the combined effects of sampling a greater fraction of the gel space and hindered transport (volume exclusion) effects. Repeating twice both steps afforded the second generation, which was functionalized by N-acetylgalactosamine (Figure 7). Differences occur in the P–O stretching frequency between phosphatidylethanolamine (1227 cm−l) and phosphatidylserine (1220–1180 cm−1). A phosphate group is also a component of the lipid bilayer which creates cellular membranes. Because of the good compatibility between MALDI detection and diamond nanoparticles, phosphopeptides adsorbed on the PA-coated diamond nanoparticles were directly analyzed without removal of the solid supports. Song, ... H.F. Zou, in Comprehensive Sampling and Sample Preparation, 2012. The 2' hydroxyl group is right next to the electrophilic phosphorus atom, poised in a good position to make a nucleophilic attack, breaking the RNA chain and forming a cyclic phosphate diester intermediate (see figure below). The sugars are joined together by phosphate groups that form phosphodiester bonds between the third and fifth carbon atoms of … DNA is double stranded, whereas RNA is single stranded. Mono-phosphate nucleotides are … Examine the view of DNA labeled "phosphate group". Each nucleotide has three major parts: a sugar molecule, a phosphate group and a cyclic compound called a nucleobase, or base. Vibration of the P–OH group gives rise to absorption at 2700–2560 cm−l. Both RNA and DNA backbone consists of alternating groups phosphates and sugars. A phosphate group is also a key component of life itself. The standards were prepared in such a way so as to obtain concentrations of 0, 10, 20, 30, 40, and 50 μg m L− 1 of p-nitrophenol. The IR spectra of complex lipids are not sensitive to variations in acyl chain length, unsaturation, or the presence of α,β-unsaturated ether links. Other electrophoretic parameters, such as applied field strength and temperature, have an effect on the mobility of the different chain length nucleic acids and on the separation efficiency. DNA has T , C , A and G. 2)the pentose sugar . Phosphate Group Structure In its free state, a phosphate group is centered around the phosphate atom, with 4 … Which of the following are found in both DNA and RNA? The same method is also used for the synthesis of dendrimers possessing selenium, oxygen,15 or boron hydride16 instead of sulfur linked to phosphorus. Quaternary amines such as phosphatidylcholine or sphingomyelin have a doublet at 1087 and 1053 cm−1 and a sharp band at 961 cm−l. Most heterogeneous of … Oligonucleotide primers are easily labeled on the 5′-phosphate group with biotin, digoxygenin, dinitrophenol, other haptens, fluorescein, other fluorophores, and many other reagents. 3. ribose deoxyribose phosphate group nitrogenous base 2 See answers sidharth3499 sidharth3499 THYMINE IS NOT PRESENT IN RNA BUT FOUND IN DNA RIBOSE SUGAR-RNA DEOXYRIBOSE SUGAR -DNA. DNA and RNA are nucleic acids. One of the major structural differences between DNA and RNA is the sugar, with the 2-deoxyribose in DNA being replaced by ribose in RNA. Assignment of acylglycerol bands in infrared spectra. However, a single RNA molecule can, by complementary base pairing, form intrastrand double helixes, as in tRNA. D. Which nucleotide in Figure 13-1 indicates the nucleic acid above is RNA? It was proposed by Salamonczyk et al. RNA structure. They are comprised of nucleotide chains linked via phosphodiester bonds between 5′ phosphate group … The formation of higher-order structures by nucleic acids will cause considerable deviation from this behavior, and indeed electrophoresis is used to ascertain the physical form of DNA. Sugars linked by phos-phates form a common backbone that plays a … Aikaterini Koutsaviti, ... Vassilios Roussis, in Bioactive Seaweeds for Food Applications, 2018. Carbon residues in the pentose are numbered 1′ through 5′ (the prime distinguishes these residues from those in the base, which are numbered without using a prime notation). -The backbone of DNA and RNA is composed of sugar and phosphate groups. A phospholipid isolated from P. palmata (1), along with other polar lipids, exhibited strong antiinflammatory effect on RAW 264.7 macrophage cells by downregulating iNOS and thus the levels of NO, a signaling factor that plays essential part in the pathogenesis of inflammation (Banskota et al., 2014). Synthesis of phosphate based dendrimers by a convergent process in the solid phase. Unlike double-stranded DNA, RNA is a single-stranded molecule in many of its biological roles and consists of much shorter chains of nucleotides. The favorable results of this technique for capturing phosphopeptides demonstrated that it promises to be a convenient tool for mapping protein phosphorylation sites. I.J. One of the main functions of a phosphate group within cells is as an energy storage molecule. Figure: DNA and RNA: A nucleotide is made up of three components: a nitrogenous base, a pentose sugar, and one or more phosphate groups. In fact the 3' ends of DNA and RNA molecules have hydroxyl groups (-OH), whereas all the other nucleotides have phosphate groups attached at the 3' position. In DNA, sugar is called deoxyribose, which is a cyclic pentose (5-carbon sugar). This sugar molecule is linked to the phosphate group. There are two types of nucleic acids: DNA and RNA. A consequence of this behavior is that for high molecular weights, the ‘grouped’ of the DNA chain no longer samples a distribution of pore space, and the mobility becomes independent of chain length. DNA and RNA both use a different but overlapping set of bases: Adenine, thymine, … Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. Each ribonucleotide is lost from: Ribose pentose sugar. For example, the CH2 rocking band at 720 cm−1 of 2,3-dipalmitoyl-dl-1-phosphatidylethanolamine is split into a doublet at low temperatures but this band changes into a singlet at room temperature. The nucleotides consist of three components – a 5 carbon sugar (Ribose in RNA and Deoxyribose in DNA), a phosphate group, and a nitrogenous base (Purines –A and G, Pyrimidines – C, T, and U). Figure \(\PageIndex{1}\): DNA and RNA: A nucleotide is made up of three components: a nitrogenous base, a pentose sugar, and one or more phosphate groups. Free amine groups as present in phosphatidylserine or phosphatidylethanolamine show a single sharp absorption band at 1075 cm−l. The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. RNA uses the bases adenine, uracil, guanine, and cytosine. Roth, in Encyclopedia of Analytical Science (Second Edition), 2005. Acid phosphatases show maximum activity at acidic pH around 6 whereas alkaline phosphatases show maximum activity at alkaline pH around 11. The phosphate group is usually attached through the 5′ or 3′ hydroxyl groups of the sugar. Notice a phosphate group is a central phosphorous atom covalently bonded to 4 oxygen atoms. In DNA, the sugar molecule has one oxygen atom less, which is why it’s called deoxyribose (C5H10O4). Studies with transgenic potato have shown that the phosphate content of tuber starch can be altered in plants which show varied levels of SS and SBE activities. 12-7), giving each linear nucleic acid strand a specific polarity and distinct 5' and 3' ends. The phosphate backbone is the outside of the ladder when you see a picture of DNA or RNA. Phosphate group DNA (and RNA) are polymers made up of five-carbon sugars, organic nitrogen-containing bases, and phosphate groups. A phosphate group, in the context of biology, is a molecule composed of a phosphorous atom and four oxygen atoms. They are large molecules called macromolecules or polymers. A constituent of deoxyribonucleic acid is a number of individual phosphates. Gordon, in Encyclopedia of Analytical Science (Second Edition), 2005. The structure of DNA DNA RNA 1. However, the nitrogenous bases of phospholipids can be identified by their IR absorption spectra in the region of 900–1100 cm−1. For example, a solid phase coated with avidin or streptavidin can be used to capture hybrids containing a biotinylated primer. Nucleotides consist of a nitrogenous base, a five-carbon sugar, and a phosphate group. You can see the recycling of phosphate groups between ADP and ATP in the diagram below. Pentose sugar Both DNA and RNA contain a pentose monosaccharide in their nucleotides, which is attached to a nitrogenous base and one, two or three phosphate groups. Deoxyribose is a modified form of another sugar called ribose. Next, identify the location of the phosphate groups in the overall view of DNA labeled "original". However, no experimental details were given. This use of a phosphate group (or many) is seen in many cellular communication channels. Cost and availability are considerations that have prompted many researchers to use avidin. We use cookies to help provide and enhance our service and tailor content and ads. Messenger RNA (mRNA) Accounts for about 5% of the total RNA in the cell. they make it easier for enzymes in the cell to tell DNA and RNA apart The use of phosphoramidites as building blocks in solution was developed by Roy et al. Copyright © 2020 Elsevier B.V. or its licensors or contributors. On the basis of monomeric unit composition, they can be either DNA or RNA. Separation ranges for agarose and acrylamide gels, A.-M. Caminade, J.-P. Majoral, in Polymer Science: A Comprehensive Reference, 2012. ... phosphate groups varies; simply instead of monophosphate which indicates one phosphate unit we use diphosphate for two phosphate units and triphosphate for three (i.e. Each nucleotide contains a nucleotide base (A,T,C, or G), a sugar (deoxyribose), and a phosphate group. The ends of DNA strands are called the 5′(five prime) and 3′ (three prime) ends.
