← Human Body & HealthIf a bacterial colony, where some members possess a plasmid conferring antibiotic resistance, are lysed via phage infection, which consequence follows regarding resistance?
A)Resistance mutation rate is suppressed
B)Bacterial fitness becomes inversely related
C)Conjugation efficiency sees drastic reduction
D)Horizontal gene transfer boosts resistance✓
💡 Explanation
Phage-mediated lysis facilitates horizontal gene transfer because transduction allows DNA, including resistance plasmids, to be packaged and transferred to new bacteria, therefore increasing overall resistance. This occurs rather than suppressing mutation, altering fitness, or reducing conjugation.
