A bacterial strain was exposed to a translation inhibitor that specifically blocks entry of aminoacyl-tRNA into the A site but does not affect initiation complex formation. In pulse-chase experiments, nascent peptides remained short and ribosome-associated. Which outcome is most consistent with the requirement for peptide bond formation in primary structure elongation?
(Assume the inhibitor does not degrade mRNA.)
