According to the diagram on DNA replication, what is characteristic of where replication begins on a chromosome?
- A: It begins randomly throughout the chromosome, creating single-stranded DNA fragments.
- B: It initiates at the centromere, leading to the immediate separation of sister chromatids.
- C: It begins at multiple sites (origins), each forming a replication bubble with a fork at each end.
- D: It occurs only at the very ends of the chromosome (telomeres), leading to chromosome shortening over time.
Explanation
The diagram's text explicitly states: 'Replication begins at multiple sites origins , each forming a replication bubble with a fork at each end.'
