Vedclass · Answer

(A) In the process of $DNA$ replication,the $DNA$ polymerase enzyme can only synthesize $DNA$ in the $5' \rightarrow 3'$ direction.Because the two strands of the $DNA$ double helix are antiparallel,one strand (the leading strand) is synthesized continuously in the direction of the replication fork movement.In the given figure,$A$ represents the leading strand where continuous synthesis occurs.The other strand (the lagging strand) is synthesized in short fragments known as Okazaki fragments,which represents discontinuous synthesis,indicated by $B$.$C$ points to the original parental $DNA$ strands which act as the template for replication.$D$ represents the newly synthesized $DNA$ strands formed during the process.Therefore,the correct identification is $A \rightarrow$ Continuous synthesis,$B \rightarrow$ Discontinuous synthesis,$C \rightarrow$ Template strand,$D \rightarrow$ Newly synthesised strands.
