What is capping in the processing of hnRNA in eukaryotes?

What is capping in the processing of hnRNA in eukaryotes?
  1. Adding an unusual nucleotide to the 5'-end of hnRNA
  2. Adding adenylate residues to the 3'-end of hnRNA
  3. Removing introns
  4. Joining exons in a defined order

Solution

In eukaryotes, hnRNA undergoes capping where an unusual nucleotide (methyl guanosine triphosphate) is added to the 5'-end of hnRNA.
