WebDraw a replication bubble. Be sure to label the directionality of all strands of DNA. For one of the two replication forks, draw and label all of the proteins required the text describes as being important for DNA synthesis, and label the leading and lagging strands. 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).
