WebAccording to Watson-Crick base-pairing, which forms the basis for the helical configuration of double-stranded DNA, DNA contains four bases: the two purines adenine (A) and guanine (G) and the two pyrimidines cytosine (C) and thymine (T). Within the DNA molecule, A bonds only with T and C bonds only with G. DNA 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).
