In prokaryotic cells, DNA is unzipped and replication happens in both directions. This forms two replication forks at this replication bubble (the location on a replicating DNA molecule where the new strands will be produced). Prokaryotic DNA is circular in shape and tends to be shorter than eukaryotic DNA, so it can be duplicated much faster DNA replication occurs with the involvement of many enzymes. The DNA molecule is unzipped and therefore separated into two single strands that we will call the parent strands. These are then used as templates for the complementary base pairing that will take place. Since the A's will always go to the T's, the C's will always go to G's, and. it is the initial step of DNA replication in which double helix of DNA separated by breaking of its hydrogen bond to form replication fork with the help of helicase enzmy in order to make new copies during unzipping DNA base pairs are separated fr..
