Which of the following correctly states a difference between thefunctions of DNA Polymerase III and DNA Polymerase I?
DNA Polymerase III synthesizes the leading strand, whereas DNAPolymerase I is used for synthesis of the lagging strand (Okazakifragments).
DNA Polymerase III does not require an RNA primer, whereas DNAPolymerase I does.
DNA Polymerase III synthesizes new DNA strands in the 5â to 3âdirection only, whereas DNA Polymerase I also can synthesize DNA inthe 3â to 5â direction.
DNA Polymerase III has a 3â to 5â exonuclease activity thatserves a proofreading function, whereas DNA Polymerase I lacks thisactivity.
DNA Polymerase III is the main polymerase of the replisome,whereas DNA Polymerase I removes primers and fills in the gaps thatare left.
