X Chromosome Inactivation – Mechanism – Role of XIC and XIST
In last video we discussed about the Lyonization and overall process of X inactivation. In this video, let’s continue and understand the mechanism of X chromosome inactivation 🙂
X Inactivation – Lyonization
X Inactivation – Lyonization
Females have two X chromosomes that means they have two alleles for every gene on X chromosome and males have only one.
Therefore, X inactivation occurs in female to avoid the gene expression inequality. Let’s find out how it happens 🙂
