Which of the following is true? a) In eukaryotes, mature mRNAs typically have introns, a 5' cap, and a poly(A) tail. b) Before a prokaryotic mRNA can be translated, it must be modified by the addition of a poly(A) tail. The unusual 5'-to-5' linkage in the 5' cap protects the mRNA from exonucleases. The poly(A) tail can act as a buffer against 3'-to-5' exonucleases. The spliceosome eliminates introns from the pre-mRNA.

Processing of eukaryotic RNA yields a mature mRNA that typically has a 5' cap, a 3' poly A tail, and has removed an amount of introns has a mix of methylated groups before and after the open reading frame and the 3' poly tail has a 3' cap, a 5' poly A tail, and no introns has a 5' cap, a 3' poly A tail, and has spliced out methylated exons
