Initiation of Replication Occurs at an "Origin of Replication" Site

question 33

Multiple Choice

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:

• A)adenine-thymine pairs are held together by two H-bonds,making them easier to separate during unwinding.
• B)the AT-rich region recruits DNA polymerase to begin the process of DNA replication.
• C)the AT-rich region recruits topoisomerase to begin the process of DNA replication.
• D)GC-rich regions are impossible to replicate because of their strong H-bonds.
• E)None of the answers is correct.
