Students have asked these similar questions
Which of the following is the correct sequence for RNA splicing:
1. U2 binds to the branch site and ATP is hydrolyzed
2. U1 binds to the GU sequence at 5’ splice
3. U5/U4/U6 trimer binds
4. U2/U5/U6 are bound to lariat and 3’ site is cleaved and exons are ligated using ATP hydrolysis.
5. U1 is release, U5 shifts from exon to intron and U6 binds at the 5’ splice site
6. U4 is released, U6/U2 catalyzes transesterification, U5 binds exon at 3’ splice site, and the5’ site is cleaved.
