Inactive gene
X-inactivation (also called Lyonization, after English geneticist Mary Lyon) is a process by which one of the copies of the X chromosome is inactivated in therian female mammals. The inactive X chromosome is silenced by being packaged into a transcriptionally inactive structure called heterochromatin. As nearly all female mammals have two X chromosomes, X-inactivation prevents them fro… WebGene activation and inactivation are complicated, multistep, and tightly controlled molecular mechanisms. Increasingly it is being recognized that the promoter CpG island …
