Vedclass · Answer

(D) During $DNA$ replication,the two strands of the $DNA$ double helix are antiparallel ($5' \rightarrow 3'$ and $3' \rightarrow 5'$). $DNA$ polymerase can only synthesize $DNA$ in the $5' \rightarrow 3'$ direction. On the leading strand,synthesis occurs continuously towards the replication fork. On the lagging strand,synthesis occurs in short segments known as $Okazaki$ fragments,moving away from the replication fork. Because these fragments are synthesized in short,separate bursts,the process on the lagging strand is described as discontinuous.
