A)splicing
B)capping
C)polyadenylation
D)export to the cytoplasm
E)All of the above

Question

Quizplus · Accepted Answer

All of the above processes are necessary for eukaryotic mRNA to be functional for translation. Splicing removes introns and joins exons together to create a mature mRNA molecule. Capping involves the addition of a 7-methylguanosine group at the 5' end of the mRNA molecule. Polyadenylation adds a string of adenine nucleotides (poly-A tail) at the 3' end of the mRNA molecule. Finally, mRNA must be transported from the nucleus to the cytoplasm for translation to occur.
