the following model represents the elongation stage of protein translation.\nwhich arrow represents a trna leaving the ribosome after transferring an amino acid to a growing polypeptide chain?\nchoose 1 answer:\na arrow 1\nb arrow 2\nc arrow 3\nd arrow 4

Answer

Brief Explanations:

In the elongation stage of protein translation, tRNA carries an amino acid to the ribosome, transfers it to the growing polypeptide chain, and then leaves. Arrow 3 shows a tRNA leaving the ribosome after transferring its amino acid. Arrow 1 is a tRNA arriving, Arrow 2 is peptide bond formation, and Arrow 4 is a new tRNA arriving. So the correct arrow is Arrow 3 (Option C).

Answer:

C. Arrow 3
