Q169 / 200 · NEET 2004 · Zoology

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

  • A
    RNA primers are involved
  • B
    is facilitated by telomerase
  • C
    moves in one direction of the site
  • Correct answer
    D
    moves in bi-directional way.

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'.

Hence, the correct answer is option: 'D'.
