Question

Peptidyl transferase enzyme found on _______.

• A. Cytoplasm
• B. E.R
• C. Golgi body
• D. Ribosomes

Answer 1

The correct option is D Ribosomes

The peptidyl transferase is an aminoacyltransferase, it performs the primary enzymatic function of the ribosome, which forms peptide bonds between adjacent amino acids using tRNAs during the translation process of protein biosynthesis. Peptidyl transferase activity is carried out by the ribosome. Peptidyl transferase activity is not mediated by any ribosomal proteins but by ribosomal RNA (rRNA), a ribozyme.

So, the correct answer is option D.
