Solution

The reaction that sequentially links adjacent amino acids into the growing polypeptide chain is B. transpeptidation.

Here's a step-by-step explanation:

  1. The process begins with the formation of an aminoacyl-tRNA, which is an amino acid attached to a transfer RNA (tRNA) molecule. This is the Aminoacyl-tRNA binding.

  2. The aminoacyl-tRNA then binds to the ribosome, where protein synthesis occurs.

  3. The next step is transpeptidation. During this step, the amino acid is transferred from the tRNA to the growing polypeptide chain. This is done by forming a peptide bond between the new amino acid and the carboxyl end of the growing chain. This is the step that links adjacent amino acids together.

  4. The last step is translocation. The ribosome moves
