  • 13.2C: X-Inactivation

    The presence of extra X chromosomes in a cell is compensated for by X-inactivation in which all but one X chromosome are silenced.

    How XX human females (and other female mammals) shut down one of their X chromosomes in each cell. Disorders of sex chromosome number: Klinefelter, triple X, and Turner syndromes.

Converting differentiat...This page discusses epigenetics, which involves heritable phenotype changes without DNA sequence alteration. It covers cellular differentiation, X-inactivation, and imprinting. Converting differentiated cells to induced pluripotent stem cells faces challenges in reversing epigenetic changes. DNA methylation and histone modifications lead to stable gene expression changes, regulated by key players known as "writers," "erasers," and "readers" that modify or recognize epigenetic marks.
