Question

Why is methicillin-resistant Staphylococcus aureus (MRSA) methicillin resistant?

a.The bacteria are able to prevent entry of the drug into the cell
b.It produces a modified version of the molecule that is targeted by the drug
c.It has an enzyme that destroys methicillin
d. It actively pumps the antibiotic out of the cell

Answer 1

MRSA is methicillin resistant because it produces a modified version of the molecule targeted by the drug.

Step-by-step explanation:

Methicillin-resistant Staphylococcus aureus (MRSA) is methicillin resistant because it produces a modified version of the molecule that is targeted by the drug. When methicillin is introduced into the cell, MRSA modifies the targeted molecule in a way that renders the drug ineffective. This modification allows MRSA to survive and continue to multiply, leading to antibiotic resistance.
