Detailed explanation-1: -Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis-the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.
Detailed explanation-2: -Peptide bonds are formed when the amine group of one amino acid binds with the carbonyl carbon of another amino acid.
Detailed explanation-3: -Peptidyl transferase is the activity responsible for peptide bond formation during protein synthesis. This enzyme activity catalyzes the reaction between the amino group of the aminoacyl-tRNA in the A site and the carboxyl carbon of the peptidyl-tRNA in the P site, forming a peptide bond from an ester bond.
