Solution
The 5' cap on mRNA serves several important functions:
-
mRNA Stability: The 5' cap protects the mRNA molecule from enzymatic degradation in the cytoplasm, thus increasing its stability.
-
Exit from the Nucleus: The 5' cap is recognized by specific proteins that facilitate the export of the mRNA molecule from the nucleus to the cytoplasm.
-
Initiation of Translation: The 5' cap helps in the initiation of protein synthesis by facilitating the binding of the mRNA to the ribosome.
