1. Describe the main RNA processing steps in eukaryotic cells and why they are important. Include what could occur if there was an error in the system such as gene coding mutation for an enzyme or RNA itself occurs, the effect of drug on enzyme function, and any other random mistakes in the cell overall. 2. What is the function of the Poly-A tail on mRNA? What would it mean for RNA processing if it was longer than it should? 3. What is the function of the 5' cap? What would occur if it was not added to the pre-mRNA? 4. What would occur if a mutation occurred in the 5' splice site between the fourth exon and fourth intron of a pre-mRNA which has eight exons and seven introns ? 5. If the last nuclease processing steps in rRNA synthesis did not occur, what would take place? 6. What would arise to the secondary structure and ultimate function of tRNA if base modifications did NOT happen
