He is very likely has defect in which of the following mechanism

Ans. a. Peptidyl transferase activityRibozymes are RNA molecule with catalytic activitydeg. Ribozymes play a central role in peptide bond formation (peptidyl transferase activity).RibozymeRibozymes are RNA molecules with catalytic activityo.These generally involve transesterification reactions, and most are concerned with RNA metabolism (splicing and endoribonuclease).Recently, a ribosomal RNA component was noted to hydrolyze an aminoacyl ester and thus play a central role in peptide bond formation (peptidyl transferase)Q
