During replication of a bacterial chromosome $DNA$ synthesis starts from a replication origin site and

Moves in one direction of the site

Moves in bi-directional way

$RNA$ primers are involved

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.
