- How do Chaumeil, et al., track a "single species" of mRNA transcripts?
- How to they demonstrate the absence of transcription? What is a major drawback to this method? Do they truly demonstrate "absence of transcription?"

Q1. How do you think the Xist transcript is able to exclude RNA Pol II and other transcription components from a "defined" region? How would you go about testing your hypothesis?
Q2. In relation to Q1 - what do you think the Xist domain is comprised of?
