<u>b. synthesizes new DNA only in the 5' to 3' direction.</u>
Explanation:
DNA Polymerase III is involved in replication of DNA, it is involved in the proofreading of the replication mistakes by activity reading 3' to 5' and synthesizing 5' to 3' . It can add nucleotides to the strand at the rate of about 1000 nucleotides per second.
