In the process of exploring the birth of the earliest galaxies in the universe, to understand the planetary systems, explore planets that are capable of supporting life, and to learn whether life began elsewhere in the solar system have helped us advance and build our civilization.
During the process of replication, the double stranded DNA unwinds and parts itself by the action of enzyme called as Helicase. The unwinding or separation of DNA forms a replication bubble and at the edge of the replication bubble is the replication fork.
DNA replication starts at the point called as origin of replication or ORI at the replication fork. DNA polymerase is the enzyme that plays a key role in DNA replication. DNA continues to replicate until the entire new strand is not formed.
