During replication of a bacterial chromosome DNA syntnthesis stars from a replication origin site and

A

RNA primer are involved

B

is facilitated by telomerase

C

moves in one direction of the site

D

moves in bi- directional way

Text Solution

Verified by Experts

The correct Answer is:
A
The events for initiation of DNA replication in prokaryotes may be classfied into (a) pre- priming (occurring only at the origin), (b) priming (recurring with the initiation of each Okazaki fragment during elongation phase. Unwinding of DNA is followed by the synthesis of RNA primers by RNA primase.
