Answer:
B
Explanation:
The rate of mutations on the S. Aureus population increased when exposed to antibiotics over time. This gave rise to a few mutants of the bacteria that could survive the methicillin antibiotic. This is because the mutation altered a protein target of methicilin (beta-lactam binding proteins) on which the antibiotic acted upon. These populations increased as the others were eliminated by the antibiotic – the way natural selection works. Over time, these mutations were transferred to other populations of bacteria by these MRSA through ‘sexual’ horizontal gene transfer, causing whole bacteria populations to be resistant against methicilin.
