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 … WebDec 28, 2024 · Understanding the effects of polymer processing on the structure–property relationships of polymer scaffolds is fundamental in polymer research for engineering applications in drug delivery and tissue engineering.
