During translation initiation in eukaryotes, the small ribosomal subunit identifies the start codon by recognizing which structure?
Show answer and explanation
Correct answer: The 5' methylguanosine cap
In eukaryotic cells, the 40S ribosomal subunit binds to the 5' cap and scans the mRNA for the first AUG start codon within the Kozak sequence. Prokaryotes, by contrast, use the Shine-Dalgarno sequence.
