Draw a schematic of an intron flanked by two exons in eukaryotic pre-mRNA

Draw a schematic of an intron flanked by two exons in eukaryotic pre-mRNA. Label and show the sequences of the 5’ and 3’ splice sites and branch site. Draw the pathway for a splicing reaction showing the roles of snRNP complexes U1, U2, U4, U5, and U6.
