During replication of a bacterial chromosome $DNA$ synthesis starts from a replication origin site and
A
Moves in one direction of the site
B
Moves in bi-directional way
C
$RNA$ primers are involved
D
Is facilitated by tolemerase
(AIPMT-2004)
Solution
(b) The two template strands of a replicating $DNA$ molecule are antiparallel $(5' \to 3'$ and $3' \to 5')$at the unwinding replication fork ($y$-shaped). In bacteria and many $DNA$ phages this extending is bi-directional.
