You have read a couple of epigenetics papers now, but this last one had a decidely different twist. In this paper the authors focus on an X linked gene so they can ask a complex question.
In your response please address the following points.
1) Why is the fact that the gene of interest is located on the X chromosome important.
2) What is inactivation? How is this process involved in this study?
3) What were the conclusions of the authors? What do they suggest happens next? What experiment would you do next?
