How dna structure was discovered

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). WebFeb 24, 2012 · James Watson and Francis Crick are usually given credit for discovering that DNA has a double helix shape, like a twisted ladder. The discovery was based on the prior work of Rosalind Franklin and other scientists, who had used X-rays to learn more about DNA’s structure.
