Question
The __________ reaction sequentially links adjacent amino acids into the growing polypeptide chain. A. Aminoacyl-tRNA binding B. transpeptidation C. Translocation D. peptidation
Solution
The reaction that sequentially links adjacent amino acids into the growing polypeptide chain is B. transpeptidation.
Here's a step-by-step explanation:
-
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.
-
The aminoacyl-tRNA then binds to the ribosome, where protein synthesis occurs.
-
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.
-
The last step is translocation. The ribosome moves
