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 … Webb3 sep. 2024 · This crystallography technique uses x-rays to form a diffraction pattern which indicates a molecule’s structure. This technique was used to examine a DNA molecule, …
