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). WebThis mitochondrial DNA is more like bacterial DNA—a single long, circular piece of DNA made up of two strands of DNA. A DNA strand is a long, thin molecule—averaging only about two nanometers (or two billionths of a meter) in width. That is so thin, that a human hair is about 40,000 times as wide.
