Why do females inactivate an X chromosome?
Why do females inactivate an X chromosome?
X-inactivation ensures that females, like males, have one functional copy of the X chromosome in each body cell. Because X-inactivation is random, in normal females the X chromosome inherited from the mother is active in some cells, and the X chromosome inherited from the father is active in other cells.
Why does X chromosome inactivation happen?
X-chromosome inactivation occurs randomly for one of the two X chromosomes in female cells during development. Inactivation occurs when RNA transcribed from the Xist gene on the X chromosome from which it is expressed spreads to coat the whole X chromosome.
Why is it important that X inactivation occur?
X chromosome inactivation prevents females from having twice as many gene products as males, who only have a single copy of the X chromosome.
