Steps of x inactivation
網頁Definitions. X-chromosome inactivation (XCI) is the process by which one of two X-chromosomes is transcriptionally silenced in female mammals, equalizing the dose of X-linked genes in females (XX) and males (XY). XCI takes place early in embryonic development when each cell chooses to inactivate one of the X-chromosomes. 網頁X Chromosome Inactivation Part 1: Making and Breaking the Silence Jeannie Lee (Harvard) 1 - X Chromosome Inactivation: Making and Breaking the Silence Watch on Duration: …

網頁2012年6月15日 · In mice, the X chromosomes in female cells go through sequential steps of inactivation and reactivation. Depending on the developmental time window, imprinted or random X chromosome inactivation (XCI) is initiated, and both processes lead to an inactive X chromosome that is clonally inherited. long term weather forecast alps網頁Video created by 墨尔本大学 for the course "基因表达的表观遗传调控".
