WebOct 7, 2024 · Step 1: Replication Fork Formation Before DNA can be replicated, the double stranded molecule must be “unzipped” into two single strands. DNA has four bases called adenine (A), thymine (T), cytosine (C) and guanine (G) that form pairs between the two strands. Adenine only pairs with thymine and cytosine only binds with guanine. WebIn this animation, we consider how bacteria achieve the feat of coupling of DNA replication at the replication fork as the lagging and leading strand and syn...
