Properties of dna and rna ligases
WebLigases promega enzyme resource guide ligases introduction dna ligases are primarily responsible for joining the gaps that form in dna during replication the 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).
