Post-Transcriptional RNA Processing
The Chemistry of the Primary RNA Transcript Splicing Reaction and Alternative Splicing
Problem : The splicing reaction results in the formation of two structures. Starting with a structure composed of two exons (exon 1 and exon 2) that are separated by an intron, what will be the composition (intron, exon 1, exon 2) or the two splicing products?
Problem : Describe the event that takes place during the first splicing step.
Problem : What is the name of the looped structure that is formed after the first splicing step?
Problem : Describe the event that occurs in the second splicing step.
Problem : What is the benefit of alternative splicing? Could there also be drawbacks to alternative splicing?
