Biology Question on Molecular Basis of Inheritance
During replication of a bacterial chromosomes DNA synthesis starts from a replication origin site and
Is facilitated by telomerase
Moves in one direction of the size
Moves in bi-directional way
RNA primers are involved
Moves in bi-directional way
Solution
In contrast to the linear DNA found in vertebrates, bacterial chromosomes consist of circular DNA. The replication process commences at a specific location known as the origin. However, instead of proceeding in a single direction around the chromosome, it occurs in two directions. This phenomenon is referred to as bidirectional replication, involving two replication forks moving away from the origin in opposite directions. Ultimately, these forks converge at the base of the chromosome, marking the conclusion of replication as the two chromosomes separate. Additionally, it's important to note that the bacterial chromosome can initiate multiple replication forks simultaneously.
