Final answer:
During a cell division event, the chromosome replicates the two strands, producing two identical DNA molecules.
Step-by-step explanation:
During DNA replication, each strand of the double helix serves as a template for the synthesis of a new strand. The new strand is complementary to the parental strand, resulting in two identical DNA molecules, each having one parental strand and one newly synthesized strand.
In bacterial cells, the DNA replication process is simplified because they have a single, circular DNA chromosome. After replication, the two DNA copies move into two different cells during cell division.
Therefore, during a cell division event, the chromosome replicates the two strands, producing two identical DNA molecules.
