[Check all that apply] caps and tails:
facilitate the export of the mRNA from the nucleus
Translated into proteins with the rest of the RNA
protect the mRNA from degradation by cellular enzymes
A group of extra nucleotides added to the ends of RNA
help ribosomes bind to the mRNA
Alternative RNA splicing
