WebRNA Splicing of the introns Capping the 5' End[edit] During capping, a 7-methylguanosineresidue is attached to the 5'-terminal end of the primary transcripts.This is otherwise known as the GTP or 5' cap. The 5' cap is used to increase mRNA stability. Further, the 5' cap is used as an attachment point for ribosomes.[1] WebUsing the information provided in the introduction under “MC1R Gene,” explain how the mutant MC1R protein directly affects a rock pocket mouse’s coat color. The amino acid changes in the MC1R protein may change the structure and function of the protein. This leads to increased production of eumelanin, which results in the dark color. 14.
