"Watch this video about 3.6 Stages of X inactivation - initiation and spreading of silencing for Week 3 - Dosage Compensation in 基因表达的表观遗传调控. X chromosome inactivation is a really well-characterised epigenetic process that is now used as a model system to study epigenetic processes that are relevant more broadly. This is because it uses many epigenetic mechanisms, at many levels, to achieve really stable silencing of a whole chromosome. We’ll learn about this process and how it occurs in a mouse in great detail, which will greatly add to the mechanistic understanding gained in week two. We will then briefly discuss alternate mechanisms for dosage compensation that occur in other organisms. "
