Four weeks later, she returns for her first follow-up appointment in panic because her eyes have taken on an orangered hue. Which of the following describes the mechanism of action of the drug most likely responsible for this side effect?? A: Inhibition of RNA polymerase, B: Inhibition of arabinosyltransferase, C: Inhibition of mycolic acid synthesis, D: Inhibition of topoisomerase, E: Inhibition of squalene epoxidase,  <response>: This is a question about the side effects of antituberculosis medications. The patient developed redorange discoloration of the eyes after starting treatment.
