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

Options

  1. ARNA primers are involved
  2. Bis facilitated by telomerase
  3. Cmoves in one direction of the site
  4. Dmoves in bi-directional way.

Correct answer

D. moves in bi-directional way.

Step-by-step solution

Bacterial chromosomes are circular. DNA replication begins at certain fixed unique points and is called origin. In bacteria, replication occurs in bidirectional way and two separated strands between the two forks appear as a bubble under the microscope. So, the correct answer is 'Moves in bi-directional way'.
