How a molecule of dna replicates

WebImage of a cell undergoing DNA replication (all the chromosomes in the nucleus are copied) and chromosome condensation (all the chromosomes become compact). In the first image, there are four decondensed, stringy chromosomes in the nucleus of the cell.

Based on the Replicon Model, a positively active initiator molecule contacts with a particular spot on a circular chromosome called the replicator to start DNA replication. It is a replication initiation factor which promotes the unwinding of DNA at oriC. The DnaA proteins found …
