Question:
Explain the processing of heterogeneous nuclear RNA (hnRNA) into a fully functional mRNA in eukaryotes. Where does this processing occur in the cell?
Explain the processing of heterogeneous nuclear RNA (hnRNA) into a fully functional mRNA in eukaryotes. Where does this processing occur in the cell?
Show Hint

Solution and Explanation
Steps of Processing:
Capping: Addition of a 5\(\prime\) methyl guanosine cap.
Splicing: Removal of introns and joining of exons.
Polyadenylation: Addition of a poly-A tail at the 3\(\prime\) end.
Location: The processing occurs in the nucleus of eukaryotic cells.
