Which of the following enzymes is essential for the formation of the peptide bond during protein synthesis?
- A.Peptidyl transferase
- B.DNA polymerase
- C.RNA polymerase
- D.Aminoacyl-tRNA synthetase
Show correct answer & step-by-step solution
Correct answer: A — Peptidyl transferase
Solution
- Protein synthesis involves the translation of mRNA into a polypeptide chain.
- Peptidyl transferase is the catalytic component of the ribosome.
- It catalyzes the formation of a peptide bond between the amino acid on the A-site tRNA and the growing chain on the P-site tRNA.
- Hence the answer is (A).
