← ScienceWhich consequence result from weakened hydrogen bonds during DNA replication?
A)Increased replication fork stalling✓
B)Enhanced mismatch error correction
C)Reduced telomere shortening rate
D)Accelerated polymerase proofreading efficiency
💡 Explanation
Weaker hydrogen bonds increase incorrect base pairing frequency, therefore increasing replication fork stalling, because DNA helicase spends more time disrupting inappropriately paired bases, rather than simply separating the correct base pairings. Other processes become normal.
