WebDuring DNA replication, a gamete endured a single point mutation in a segment of protein producing DNA, changing the original triplicate coding sequence "CTC" to "CAC" - for which an "A" was substituted for the "T". After this gamete completed cellular division, one of the resulting mutated gametes was the lucky sperm that fused with an egg in ... 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). try ortho
