Question

(D) During $DNA$ replication, the two strands of the double helix are antiparallel. $DNA$ polymerase can only synthesize new $DNA$ in the $5' 	o 3'$

Vedclass · Accepted Answer

Polymerization occurs in $5' 	o 3'$ direction and explains replication in $3' 	o 5'$ direction.

Vedclass · Answer

(D) During $DNA$ replication, the two strands of the double helix are antiparallel. $DNA$ polymerase can only synthesize new $DNA$ in the $5' 	o 3'$ direction. One strand, the leading strand, is synthesized continuously. The other strand, the lagging strand, is synthesized discontinuously in short segments known as Okazaki fragments. These fragments are synthesized in the $5' 	o 3'$ direction, which allows the overall replication of the template strand that runs in the $3' 	o 5'$ direction.
