DNA - Wikipedia DNA is a long polymer made from repeating units called nucleotides, each of which is usually symbolized by a single letter: either A, T, C, or G. 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. ... DNA function & structure (with diagram) (article) | Khan Academy A molecule of DNA is a bunch of nucleotide monomers, joined one after another into a very long chain. There are four nucleotide monomers The English language has a 26 letter alphabet. In contrast, the DNA "alphabet" has only four "letters," the four nucleotide monomers. They have short and easy to remember names: A, C, T, G.
