Replication begins at the origin of replication. The DNA helicase unwinds the double helix into two single strands. DNA polymerase III synthesizes one strand continuously, while RNA primers and DNA polymerase I are used to synthesize the other strand in fragments. DNA ligase joins the fragments together to form a complete double helix copy of the original DNA.
