Final answer:
In prokaryotes, replication occurs through a process called binary fission and starts at the origin of replication on the circular chromosome. The replication proceeds in both directions at once.
Step-by-step explanation:
In prokaryotes, replication occurs through a process called binary fission. This process begins at the origin of replication on the circular prokaryotic chromosome.
The replication proceeds in both directions at once, resulting in two identical copies of the chromosome.
