Rifampin

Question

Rifampin:
A)inhibits RNA synthesis
B)inhibits all nucleic acid synthesis
C)disrupts of cell membrane function
D)acts as an antimetabolite

Accepted Answer

Rifampin inhibits RNA synthesis specifically by binding to the beta subunit of bacterial RNA polymerase, which prevents the enzyme from initiating transcription. It does not inhibit all nucleic acid synthesis or act as an antimetabolite. It also does not disrupt cell membrane function.
