In the oocyte after fertilization, the paternal X chromosome is reactivated, reversing male meiotic sex chromosome inactivation (MSCI). 2. In the inner cell mass (ICM) of the epiblast after imprinted XCI in preimplantation development, the Xi is reactivated.

WebDefective chromosome segregation during mitosis has been shown to cause DNA damage that induces structural rearrangements of chromosomes (s-CIN). In contrast, whether DNA damage can disrupt mitotic processes to generate whole chromosomal instability (w-CIN) is unknown. Here, we show that activation of the DNA-damage response (DDR) during ...
