Question

1 How many replication forks are in bacteria?
2 how many replication forks are in one replication bubble?

1. The bacterial chromosome has commonly one origin of replication. However, the replication occurs in both directions from the origin. As a result, there are two forks of replication in the bacterial chromosome.

2. One replication bubble that is formed at the origin of replication contains two replication forks.
