Write your answer like this 1 2 3 4 5 6 

  • 1. U6 snRNA cuts at the 3’ end of the intron and joins the two exon sequences
  • 2. U4/U6 and U5 bind to form the completed spliceosome 
  • 3. U1 and U4 depart the spliceosome - the  5’ end of the intron is joined to the branch point
  • 4. U1 snRP base pairs with the 5’ G at the start of the intron 
  • 5. U2 snRP binds the branch point A 
  • 6. the snRNPs rearrange, "loop out” the intron and cut the intron at the 5’ end
