What is the primary mechanism through which quinolones exert their antibacterial effect?

Show Answers

Blocks the activity of DNA gyrasePrevents bacterial protein productionStops synthesis of the bacterial cell wallInterferes with bacterial folic acid absorption

Explanation

Quinolones act by targeting DNA gyrase, an essential enzyme for bacterial DNA replication. This inhibition disrupts the replication process, leading to bacterial cell death. They do not affect protein synthesis, cell wall formation, or folic acid uptake.
