Neomycin is the antibiotic which inhibits the translation of bacterial cell so that it can not affect the host cell.

1. Neomycin inhibits DNA replication.
2. Neomycin inhibits RNA transcription.
3. Neomycin inhibits protein translation.
4. Neomycin inhibits lipid synthesis.

Correct answer: Neomycin inhibits protein translation.

Solution

Neomycin is an aminoglycoside antibiotic that interferes with bacterial ribosomes, preventing proper translation of mRNA into protein. That means it inhibits protein synthesis, not DNA replication, transcription, or lipid synthesis.
