Which of the following enzymes are required in protein synthesis?
I. Ligase 
II. Permease
III. Endonuclease 
IV. Ribozyme
V. RNA polymerase 
VI. Peptidyl transferase
VII. Amino acid activating enzyme
Choose the correct option.

Enzymes required in protein synthesis are ribozyme , peptidyl transferase and amino acid activation enzyme. 23rRNA act as ribozyme, it is responsible for catalyzing the linkage of two adjacent amino acids by a peptide bond during translation. The enzyme peptidyl transferase catalyzes peptide bond formation between the adjacent amino acids. Amino acid activation enzyme  binds ATP to the amino acid to form an amino acid- AMPcomplex.
