During replication of a bacterial chromosome DNA synthesis starts from a replication origin site and (a) RNA primers are involved (b) is facilitated by telomerase (c) moves in one direction of the site (d) moves in bidirectional way.
Option D Prokaryotic DNA acts as a single replicating unit called replicon. Each replicon has a particular region where replication starts. It is called origin of replication or ori. In the region of ori, there is a particular nucleotide sequence called autonomic replicating sequence or ARS. Replication proceeds bidirectionally from each ori. A replication fork is produced on each side of ori. Replication will continue till a replication fork meets another replication fork
