Question: how mrna is processed in eukaryotes?
Answer: Eukaryotic mRNA precursors are processed by 5′ capping, 3′ cleavage and polyadenylation, and RNA splicing to remove introns before being transported to the cytoplasm where they are translated by ribosomes. ... Nascent pre-mRNA transcripts are associated with a class of abundant RNA-binding proteins called hnRNP proteins.
