Based on discussion in this chapter, Why are genes for rRNA and tRNA considered to be genes even though they do not produce polypeptides?
- Open Question

- Open Question
In one to two sentences each, describe the three processes that commonly modify eukaryotic pre-mRNA.
- Open QuestionA number of experiments have demonstrated that areas of the genome that are transcriptionally inactive are also resistant to DNase I digestion. However, transcriptionally active areas are DNase I sensitive. Describe how DNase I resistance or sensitivity might indicate transcriptional activity.
