1. Suppose you repeat the experiment in problem 28 and find the same size RNAs are made at both temperatures. Provide two possible explanations for this unexpected finding.
2. What product would DNA–RNA hybridization produce in a gene with five introns? No introns? Draw these hybrid molecules.
3. Would introns be more or less likely than exons to accumulate mutations through evolutionary time?
4. Enhancers can often exert their effect from a distance; some enhancers are located tens of thousands of bases upstream from the promoter. Propose an explanation to account for this.
