1. Which modification occurs as part of transcriptional termination? Explain this modification and how it is tied to transcriptional termination. 2) What genetic elements does the spliceosome recognize on a pre-mRNA and what does it do at/with those sequences? 3) What is alternative splicing and how does it contradict the old "one gene, one protein" rule. 4) What roles do the 5'-cap and poly(A) tail play in the mature mRNA?
