Question

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

• A. Moves in one direction of the site
• B. Moves in bi-directional way
• C. Involves RNA primers
  
• D. Is facilitated by telomerase

Answer 1

Answer: (B)

Moves in bi-directional way

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'.
