Question

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

Options

• is facilitated by telomerase

• moves in one direction of the site

• is facilitated by DNA ligase

• RNA primers are involved

Answer 1

During replication of a bacterial chromosome DNA synthesis starts from a replication origin site and RNA primers are involved.

Explanation:

DNA replication requires RNA primers to provide a starting point for DNA polymerase. Bacterial replication proceeds bidirectionally from the origin, and telomerase is not used for bacterial chromosomes.
