Given what we know, we can confirm that during the elongation stage of translation, what is elongated is in fact the amino acid chain that is being formed.
<h3>What is an amino acid chain?</h3>
To summarize it very briefly, translation is a process in which cells produce proteins. The proteins in question are produced from chains of amino acids. As more amino acids are added to this chain in order to form the protein, it becomes elongated.
Therefore, we can confirm that during the elongation stage of translation, what is elongated is in fact the amino acid chain that is being formed.
