Question

True or false: Peptide bond formation is catalyzed by the enzymatic activity of an RNA molecule. False True

Answer 1

True. Peptide bond formation during protein synthesis is catalyzed by the ribosome, which is a complex of ribosomal RNA (rRNA) and proteins. The catalytic activity of the ribosome is primarily attributed to the rRNA, making it an example of a ribozyme. Therefore, it is true that peptide bond formation is catalyzed by the enzymatic activity of an RNA molecule.
