Elongation Consists of Three Steps: (1) a Charged TRNA Enters

Multiple Choice

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.
