Web7. Initiation STEP 1 Formation of replication fork. Before DNA can be replicated, the double stranded molecule must be "unzipped" into two single strands. In order to unwind DNA, these interactions between base pairs must be broken. This is performed by an enzyme known as DNA helicase. WebJan 27, 2006 · Biophysical Terms of Replication Fidelity The specifics of the biochemical mechanisms by which any DNA polymerase operates can, in principle, be described mathematically. Numerous studies have been employed to delineate quantitative parameters governing polymerase mechanisms.
