WebThe lagging strand has the DNA polymerase running away from the fork, so it has to come off and reattach every time to the newly exposed strand. Does the lagging strand need a primer? Yes, the lagging strand needs a new primer everytime a new fragment is … WebThe lagging strand is the strand of new DNA whose direction of synthesis is opposite to the direction of the growing replication fork. Because of its orientation, replication of the lagging strand is more complicated as compared to that of the leading strand.
