c. at random locations around the circle
d. one quarter of the way around the DNA circle from the origin
e. near Arnold

Answer 1

In bacterial chromosome replication, replication terminates at the terminus, located across the circular chromosome from the origin.

Step-by-step explanation:

In replicating bacterial chromosomes, replication terminates at a specific region called the terminus, which is located across the circular chromosome from the origin of replication. Replication begins at a single origin of replication, proceeding bi-directionally with two replication forks moving away from the origin. The process continues in both directions around the chromosome until the replication forks meet at the terminus. This binary fission in prokaryotes ensures that the entire chromosome is replicated before the cell divides.
