← ScienceWhich outcome occurs from weakened hydrogen bonding between DNA strands?
A)Elevated spontaneous mutation event frequency✓
B)Increased protein folding structural rigidity
C)Reduced cellular respiration efficiency
D)Accelerated ribosome synthesis regulation
💡 Explanation
Weak hydrogen bonds cause DNA to unwind more easily, therefore higher mutation rates become statistically probable due to replication errors, rather than structurally rigid proteins; it is the physical instability of the double helix.
