Webamong bases, are arranged so that one cannot break without simultaneously breaking many others-Consequently DNA double helices that a re 10 or more base pairs long are quite stable at room temperature-Note that the atoms positioned in the major and minor grooves as a result of base pairing interactions can act as H donors or acceptors 3 Main Functions … WebDNA is a long polymer made from repeating units called nucleotides. The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. In all species it is composed of two helical chains, bound to each other by hydrogen bonds.Both chains are coiled around the same axis, and have the same pitch of 34 ångströms (3.4 nm).

The general structure of a ribonucleotide consists of a phosphate group, a ribose sugar group, and a nucleobase, in which the nucleobase can either be adenine, guanine, cytosine, or uracil. Without the phosphate group, the composition of the nucleobase and sugar is known as a nucleoside. The interchangeable nitrogenous nucleobases are derived from two parent compo… WebApr 11, 2024 · Chemical structure of DNA [41] • DNA is a linear, oligomer-like chain of nucleotides. Composed of a ribose sugar, a phosphate group, and an attached nitrogenous heterocyclic base.• DNA and ribonucleic acid (RNA) are nucleic acids.• Aptamers are short sequences of artificial DNA, RNA.• WebThe four heterocyclic bases in DNA nucleotides (or nucleosides) are adenine (A), guanine (G), cytosine (C), and thymine (T). Figure 23.04 Each bonds to the C1' of deoxyribose at N* as shown below for adenine (Figure 23.05). The heterocyclic bases in RNA nucleotides (or nucleosides) similarly bond to ribose.
