Eukaryote hnRNA Processing

• 5’ Cap:
  • Guanylyltransferase
  • 3’Gpp-p5’
• Poly A Tail
  • RNA Pol II transcribes past 3’ end of coding region of DNA
  • mRNA is cleaved by an endonuclease downstream of AAUAAA.
  • CPSF - cleavage polyadenylation specific factor
  • Poly A tail added by Poly A Polymerase
