A) elongation of the polypeptide
B) base pairing of activated methionine-tRNA to AUG of the messenger RNA
C) binding of the larger ribosomal subunit to smaller ribosomal subunits
D) covalent bonding between the first two amino acids
E) the small subunit of the ribosome recognizing and attaching to the 5' cap of mRNA

Question

Quizplus · Accepted Answer

The first event to take place in translation in eukaryotes is the recognition and attachment of the small subunit of the ribosome to the 5' cap of mRNA. This helps to position the ribosome at the correct starting point for translation. The correct base pairing of methionine-tRNA to the AUG codon, binding of the larger ribosomal subunit, elongation of the polypeptide, and covalent bonding between the first two amino acids all occur after this initial event.
