Translation

AP Biology· difficulty 3/5

During translation, the peptide bond is formed

A
$By spontaneous condensation between adjacent amino acids in the A site$
B
$By aminoacyl-tRNA synthetase activity charging tRNAs with amino acids$
C
$By peptidyl transferase activity of the large ribosomal subunit (rRNA)$

D
$By GTP hydrolysis catalyzed by elongation factor EF-Tu in the ribosome$

Explanation

The 23S rRNA in bacteria (28S in eukaryotes) catalyzes peptide bond formation — making the ribosome a ribozyme.
