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

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.
