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 synthesis is initiated at the specific points within the DNA strand and is known as ‘origins’, which are present within the replication complex. The enzyme DNA Helicase, which unwinds the double-helical structure and exposes each of the two strands, so that they can be used as a template for the process of replication.
