WebMay 31, 2016 · DNA replication is bidirectional (There are two replication forks per circular DNA genome and replication involves leading/lagging strands, Okazaki fragments, DNA ligase, etc.). This process of DNA replication is very similar to that which occurs in the host cell - which is not surprising as the virus is using mainly host machinery except for ... WebOverview. DNA replication has three main steps: initiation, elongation, and termination. Replication in prokaryotes begins when initiator proteins bind to the single origin of replication (ori) on the cell’s circular chromosome. Replication then proceeds around the entire circle of the chromosome in each direction from two replication forks ...
