During replication of DNA, which one of the following enzymes polymerizes the Okazazki fragments?
Correct Answer: DNA Polymerase III
Description: Okazaki fragments are sho segments of DNA synthesized on the lagging strand, during the process of DNA replication. DNA polymerase III is a highly "processive" enzyme that has a 1 g unit which acts as a clamp loader for the lagging strand Okazaki fragments, helping the two b subunits to form a unit and bind to DNA. The polymerization of okazaki strands are done by DNA polymerase III.
