Homework Answers

Answer #1

Answer - Mechanism of action of Chloramphenicol

Option B - Blocks the peptidyl transferase of bacteria.

Chloramphenicol is a bacteriostatic drug which inhibits protein synthesis in bacteria by inhibiting peptidyl transferase activity of bacterial ribosome.

Answer - Mechanism of action of Cycloheximide

Option C - Blocks the peptidyl transferase of 80S eukaryotic ribosome

Cycloheximide is a protein synthesis inhibitor in Eukaryotes whose mechanism of action is similar to Chloramphenicol. It inhibits translation elongation by binding to E site of ribosome.

Answer - Mechanism of action of Puromycin

Option B - Blocks the “P” site

Puromycin is a ribosome-targeting antibiotic that quantitatively deacylates the P-site peptidyl-tRNA. It acts on Eukaryotes as well as prokaryotes.
