The shape of dna
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 … WebThe April 25, 1953 issue of Nature published Crick and Watson’s 900-word article, “A Structure for Deoxyribose Nucleic Acid.”.
