Question

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

Hint:

RNA processing ensures the stability and translatability of mRNA before it moves to the cytoplasm for translation.

Answer 1

Processing Stages: Capping: A 5' methyl guanosine cap is added. Splicing: Introns are removed, and exons are joined. Polyadenylation: A poly-A tail is added to the 3' end. Site: This processing takes place within the nucleus of eukaryotic cells.
