Question

Tetracycline inhibits _______

• A. Cell wall synthesis
• B. Protein synthesis
• C. DNA replication
• D. RNA synthesis

Hint:

Tetracycline inhibits bacterial protein synthesis by acting on the \(30S\) ribosomal subunit.

Answer 1

The Correct Option is B

Concept:
Tetracycline is a broad-spectrum antibiotic that acts on bacterial ribosomes.

Step 1: Bacterial protein synthesis occurs on ribosomes.

Step 2: Tetracycline binds to the \(30S\) ribosomal subunit.

Step 3: It prevents attachment of aminoacyl-tRNA to the ribosome.

Step 4: This stops addition of amino acids to the growing peptide chain.

Step 5: Therefore, tetracycline inhibits protein synthesis. \[ \boxed{\text{Protein synthesis}} \]
