The amino acids of a growing polypeptide chain are held together by what kind of bond during the elongation stage of translation
kifflom [539]

Answer: Peptide bond

Explanation: A peptide bond is the covalent chemical bond  bond that holds together two amino acids which occurs when the carboxylic group of one molecule reacts with the amino group of the other molecule, linking the two molecules and releasing a water molecule catalyzed by peptidyl transferase, an RNA-based enzyme  integrated into the growing chain.

In the elongation stage ie when Long chain polypeptides are forming , peptide bonds  are formed by linking many amino acids to each other. These peptide bonds of amino acids are  relatively unstable, and  can break spontaneously in a slow process as can be seen especially  in enzymes of living organisms in the making and breaking of bonds.
