Question
Which of the following antibiotic resistance mechanisms are most likely to be encoded by a single gene or operon that could be transferred between bacteria?
The hydrophobic outer membrane of Gram-negative bacteria
An enzyme that processes antibiotics to inactivate them
A mutation in the DNA regulating gene expression that results in fewer antibiotic-accessible membrane porins in the cell wall
Amembrane transporter that actively pumps antibiotics out of the cell
An alteration in the antibiotic's binding site on its cellular target
An enzyme that modifies an antibiotic so it can no longer bind its target
