Question

During elongation, what bonds are formed between adjacent amino acids?

Options

• Hydrogen bonds

• Disulfide bonds

• Peptide bonds

• Ionic bonds

Answer 1

Peptide bonds are formed between adjacent amino acids during elongation. The carboxyl group of one amino acid condenses with the amino group of the next amino acid, releasing a water molecule. This reaction is catalyzed by the ribosome, specifically by the peptidyl transferase activity, linking the amino acids together into a polypeptide chain.
