Question

Quizplus · Accepted Answer

Peptidyl transferase is an integral component of the large subunit of the ribosome, where it catalyzes the formation of peptide bonds between amino acids during protein synthesis, making it an enzyme in this context. Additionally, it is a ribozyme, a type of RNA molecule that has catalytic activity, fitting the description of both choices C and D.
