WebWhat does DNA look like? Your DNA structure is made up of four base pairs: adenine (A), cytosine (C), thymine (T), and guanine (G). The bases form pairs (base pairs); A with T and C with G. The base pairs connect with a sugar molecule and a phosphate molecule (making a nucleotide) that form a spiral staircase (double helix). 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). The pair of chains have …
