DNA replication occurs when DNA is copied to form an identical molecule of DNA. What are the 5 steps of DNA replication in order? Step 1: Replication Fork Formation. Before DNA can be replicated, the double stranded molecule must be “unzipped” into two single strands.

Molecular mechanism of DNA replication (article) Khan Academy

WebReplication forks are formed at each replication origin as the DNA unwinds. The opening of the double helix causes over-winding, or supercoiling, in the DNA ahead of the replication fork. These are resolved with the action of topoisomerases. Primers are formed by the enzyme primase, and using the primer, DNA pol can start synthesis. Web31 de mar. de 2024 · When DNA is replicated, the leading strand is built as a continuous piece (due to the polymerase only being able to add itself to the 3’ end), while the lagging strand is built as a discontinuous piece. The lagging strand is built discontinuously because the DNA double helix must unwind a bit before the addition of another primer. small scale industries introduction
