Quizplus · Accepted Answer

DNA polymerase III elongates the new DNA strand starting at an RNA primer during DNA replication. DNA polymerase III is the main enzyme responsible for synthesizing the leading and lagging strands of DNA during replication. It has 3' to 5' exonuclease activity that allows it to proofread its work and correct any errors.
