NEET 2004 Biology question

During replication of a bacterial chromosomes DNA synthesis starts from a replication origin site and :-

(1)Is facilitated by telomerase
(2)Moves in one direction of the size
(3)Moves in bi-directional wayCorrect
(4)RNA primers are involved

Answer: (3)

Solution

The circular bacterial chromosome has a single origin of replication (oriC). Replication begins there and two replication forks move in opposite directions around the circle (bidirectional replication, forming a theta structure) until they meet at the terminus. Telomerase acts only on the ends of linear eukaryotic
