Question

Quizplus · Accepted Answer

In prokaryotic translation, the initial amino acid incorporated into a nascent peptide is N-formylmethionine, indicating that the process involves the formylation of the methionine amino acid. This is a distinctive feature of prokaryotes, as eukaryotic translation initiates with an unmodified methionine.
