(B) The $DNA$ double helix consists of two antiparallel strands,one oriented in the $5' 	o 3'$ direction and the other in the $3' 	o 5'$ direction.$DNA$ polymerase can only synthesize $DNA$ in the $5' 	o 3'$ direction.On the leading strand,synthesis occurs continuously in the same direction as the replication fork movement.On the lagging strand,which is oriented in the $3' 	o 5'$ direction relative to the replication fork,synthesis must occur discontinuously in short segments known as Okazaki fragments,moving away from the replication fork.These fragments were discovered by Reiji Okazaki in $1968$.
