Q. Which antibiotic inhibits interaction between tRNA and mRNA during bacterial protein synthesis?

A) Tetracycline
B) Erythromycin
C) Neomycin
D) Streptomycin
Explanation

Neomycin is a broad spectrum antibiotic which was first isolated from a strain of Streptomyces fradiae. It is effective against Gram positive as well as Gram negative bacteria. Its mechanism of action is by selective inhibition of protein synthesis on the 70S (prokaryotic) ribosome by inhibiting the interaction of mRNA and tRNA during translation process.
