← Human Body & HealthWhat happens to bacterial antibiotic resistance when a mutation deactivates a cell's own DNA mismatch repair mechanism?
A)Decreased mutation rate overall
B)Slower adaptation to antibiotics
C)Decreased horizontal gene transfer
D)Accelerated development of resistance alleles✓
💡 Explanation
If the DNA mismatch repair mechanism fails due to mutation, DNA replication errors accumulate because the repair system is broken; therefore, accelerated antibiotic resistance development is likely, rather than a slower adaptation, a decreased mutation rate, or a drop in gene transfer.
