Elongation consists of three steps: (1) a charged tRNA enters the A site, (2) a peptide bond is created between amino acids in the A and P sites, and (3) the ribosome translocates to the next codon. Elongation requires several elongation factors and GTP.
-In elongation, the creation of peptide bonds between amino acids is catalyzed by
A) rRNA.
B) protein in the small subunit.
C) protein in the large subunit.
D) tRNA.

Question

Quizplus · Accepted Answer

The creation of peptide bonds during elongation is catalyzed by the ribosomal RNA (rRNA) in the large subunit of the ribosome, specifically the peptidyl transferase activity of the rRNA.
