Question

multiple choice question
tetracyclines inhibit ______.
○ replication of dna
○ folic acid synthesis
○ protein synthesis
○ cell formation

Explanation:

Tetracyclines are a class of antibiotics. Their mechanism of action involves inhibiting protein synthesis in bacteria. They bind to the 30S ribosomal subunit, preventing the attachment of aminoacyl - tRNA to the ribosome - mRNA complex, thus halting protein synthesis. DNA replication inhibitors have different mechanisms (e.g., quinolones target DNA gyrase), folic acid synthesis inhibitors are like sulfonamides, and cell formation is not the primary target of tetracyclines.

Answer:

O protein synthesis
