How does Staphylococcus aureus acquire resistance to methicillin?
A) An enzyme alteration
B) Mobile DNA element
C) Frameshift mutation
D) RNA porin

Question

Quizplus · Accepted Answer

Staphylococcus aureus acquires resistance to methicillin through the acquisition of a mobile DNA element known as a SCCmec element. This element carries genes for resistance to multiple antibiotics, including methicillin. An enzyme alteration or frameshift mutation could lead to antibiotic resistance, but these are not specifically related to methicillin resistance in S. aureus. RNA porins are not a known mechanism for antibiotic resistance.
