Explanation
The enzyme Peptidyl Transferase, which helps in the formation of peptide bond, is present in the larger subunit of ribosome (Option B).
Ribosomes are the molecular machines responsible for translating mRNA sequences into proteins. They are composed of two subunits, the larger and the smaller subunits, which come together during protein synthesis. The larger subunit of the ribosome contains the active site for peptide bond formation, which is catalyzed by peptidyl transferase.
Option A is incorrect as t-RNA is a type of RNA molecule that carries amino acids to the ribosome during protein synthesis, and it does not contain peptidyl transferase.
Option C is incorrect as the smaller subunit of the ribosome plays a role in binding the mRNA and the tRNA during protein synthesis, but it does not contain peptidyl transferase.
Option D is incorrect as mRNA is a type of RNA molecule that carries genetic information from DNA to the ribosome during protein synthesis, but it does not contain peptidyl transferase.
