What in eukaryotes has a role most similar to that of the Shine-Dalgarno sequence in prokaryotes?
A) The small subunit of the ribosome
B) The large subunit of the ribosome
C) The 5'cap of mRNA
D) The poly A tail of mRNA
E) Aminoacyl-tRNA synthetase

The 5F1F1F1S1F1F1F10 cap of mRNA in eukaryotes plays a similar role to Shine-Dalgarno sequence in prokaryotes in the ribosome binding to mRNA and initiating translation. Both sequences are involved in the recognition and binding of the mRNA to the ribosome. The small and large subunit of the ribosome are required for translation but do not have a similar role as the Shine-Dalgarno sequence. The poly A tail of mRNA and aminoacyl-tRNA synthetase are involved in different stages of translation and do not have a role similar to the Shine-Dalgarno sequence.
