Eukaryotic ribosomes recognize and initially bind to what structure on the mRNA?
A) A Shine-Dalgarno sequence
B) The 7-methylguanosine cap
C) A TATA sequence
D) A CCAAT sequence

Question

Quizplus · Accepted Answer

Eukaryotic ribosomes initially bind to the 7-methylguanosine cap, which is added to the 5' end of the mRNA during post-transcriptional processing. Shine-Dalgarno sequences are found in prokaryotic mRNA and are recognized by the small subunit of the ribosome during translation initiation. TATA and CCAAT sequences are found in eukaryotic promoter regions and are recognized by transcription factors during gene expression initiation.
