What are the roles of U1 and U2 snRNA in the splicing of mRNA? U2 binds to a 3\'

Question

What are the roles of U1 and U2 snRNA in the splicing of mRNA?

U2 binds to a 3' exon intron boundary and U1 binds to the export site

U1 binds to a 5' exon intron boundary and U2 binds to the branch point

U1 binds to U2 and the form a complex at the cap

                                U1 binds to duplexed DNA-RNA to aid in splice site skipping

U2 binds to a 3' exon intron boundary and U1 binds to the export site

U1 binds to a 5' exon intron boundary and U2 binds to the branch point

U1 binds to U2 and the form a complex at the cap

                                U1 binds to duplexed DNA-RNA to aid in splice site skipping

Explanation / Answer

Roles of U1 and U2 snRNA in the splicing of mRNA is U1 binds to a 5' exon intron boundary and U2 binds to the branch point becuase U1 first recognizes premRNA splice site and then U2 snRNA binds to the branch point
