Capping of prokaryotic monocistronic mRNA's allows correct translation in a eukaryotic translation system. This result is evidence for
A) a role for 7-methyl-GpppNp in the recognition of mRNA by eukaryotic initiation factors and/or ribosomes.
B) a role for poly A in mRNA selection.
C) a role for F-met-tRNA in protein recognition.
D) a malfunctioning prokaryotic RNA-polymerase.
E) the production of monocistronic mRNA's in eukaryotes.

Question

Quizplus · Accepted Answer

The capping of prokaryotic monocistronic mRNA's allows recognition by eukaryotic initiation factors and/or ribosomes through the 7-methyl-GpppNp cap. This indicates that there is a role for the cap in the translation of eukaryotic mRNA's, supporting choice A as the correct answer. Choice B (poly A) and choice C (F-met-tRNA) are not relevant to capping of mRNA, and choices D and E are not supported by the information given in the question.
