Question
**Initiation of replication occurs at an “origin of replication” site that typically includes an AT-rich region. Initiation benefits from these AT-rich regions because:**

- ☐ the AT-rich region recruits topoisomerase to begin the process of DNA replication.

- ☐ GC-rich regions are impossible to replicate because of their strong H-bonds.

- ☐ the AT-rich region recruits DNA polymerase to begin the process of DNA replication.

- ☐ adenine-thymine pairs are held together by two H-bonds, making them easier to separate during unwinding.

- ☐ None of the answers is correct.
