Solution

The correct option is A 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'.
