Инактивация Х-хромосомы в клетках самок млекопитающих и Эпигенетика

X inactivation is a vital process that occurs in all DNA-containing cells of the female body. It is also an important research model and tool for studying epigenetics. Epigenetics refers to processes that tell our cells how, and when, to read the DNA blueprint. The epigenetic regulation of DNA is critical in both normal development and disease. X inactivation is a type of gene dosage compensation. In humans, the sex chromosomes X and Y determine the sex of an individual - females have two
