Question

Inhibition of ___ ____ synthesis. interferes with amino acid cross linking of PG.

A) Inhibition of DNA replication.
B) Inhibition of ribosomal function.
C) Inhibition of lipid metabolism.
D) Inhibition of protein folding.

Answer 1

Antibiotics such as tetracycline and chloramphenicol interfere with bacterial protein synthesis by targeting the ribosome.

Step-by-step explanation:

The correct answer is B) Inhibition of ribosomal function.

Antibiotics such as tetracycline and chloramphenicol interfere with bacterial protein synthesis by targeting the ribosome, the cellular machinery responsible for protein synthesis.

Tetracycline blocks the A site on the bacterial ribosome, preventing the binding of the aminoacyl-tRNA complex to the ribosome, which is necessary for protein synthesis.

Therefore, the inhibition of ribosomal function, specifically the binding of tRNA to the ribosome, would interfere with amino acid cross-linking of peptidoglycan (PG), a component of bacterial cells walls, as mentioned in the question.
