Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Role of Antibiotics
- Neomycin and Kanamycin inhibit protein synthesis by targeting the ribosome.
- Rifampicin inhibits transcription by binding to RNA polymerase and preventing RNA synthesis.
- Quinolones inhibit DNA replication by interfering with DNA gyrase but do not directly affect transcription.
Step 2: Conclusion
Rifampicin specifically inhibits transcription.
