In eukaryotes which of the following is the first step in translation?
A) base pairing of activated methionine-tRNA to AUG of the messenger RNA
B) binding of the larger ribosomal subunit to smaller ribosomal subunits
C) the ribosome reaches a stop codon
D) the small subunit of the ribosome recognizes and attaches to the 5′ cap of mRNA

Question

Quizplus · Accepted Answer

The first step in eukaryotic translation involves the small subunit of the ribosome recognizing and attaching to the 5′ cap of the mRNA, which is a unique structure found only in eukaryotic mRNAs. This step is crucial for the initiation of translation as it positions the ribosome for the scanning process to find the start codon (AUG).
