Explain how the hnRNA becomes the mRNA. OR Explain the process of splicing, capping, and tailing which occur during transcription in Eukaryotes.
hnRNA is the precursor of mRNA. It undergoes: Splicing: Introns are removed and exons are joined together. Capping: an unusual nucleotide (methyl guanosine triphosphate is added to the 5´ end of hnRNA. Adenylate residues (200-300) are added at the 3´ end of hnRNA.
