During replication of a bacterial chromosome DNA synthesis

Home » Advanced Botany » Molecular Basis of Inheritance » Question

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

1. RNA primers are involved
2. is facilitated by telomerase
3. moves in one direction of the site
4. moves in bi-directional way

Correct Option: D

Replication begins at the Ori - origin of replication and proceeds on both sides from the Ori. Unidirectional replication is rare. RNA primers are involved in both prokaryotes and eukaryotes.
