1. What 3 modifications are associated with processing eukaryotic pre-mRNAs? Indicate the factors involved in each of these processing steps.
2. Which component of RNA pol II is the processing machinery associated with?
3. Indicate the consensus sequences required for addition of the poly (A) tail.
4. What are the components of the spliceosomes and which 3 sites does the spliceosome act on?
5. How do alternative splicing and poly (A) site choice contribute to a proteome that is larger than the number of genes in the genome?
6. What catalyzes splicing in group I and group II introns?
7. What are the mechanisms for RNA editing?
8. How do importins and exportins interact with Ran-GDP and Ran-GTP to move RNA across the nuclear envelope?
9. How is the exon junction complex used to signal the presence of stop codon that are incorrectly located? What is this system called?
10. What must happen for eukaryotic mRNA transcripts to be degraded?
11. How are pre-tRNA and pre-RNA transcripts processed?
12. How are pri-miRNAs processed?
