Witryna4 cze 2010 · Imprinted inactivation of the paternal X chromosome in marsupials is the primordial mechanism of dosage compensation for X-linked genes between females and males in Therians. In Eutherian mammals, X chromosome inactivation (XCI) evolved into a random process in cells from the embryo proper, where either the maternal or … Witryna1 kwi 2015 · X-chromosome inactivation (XCI) is a developmentally associated process that evolved in mammals to enable gene dosage compensation between XX and XY individuals. In placental mammals, it is triggered by the long noncoding RNA Xist, which is produced from a complex regulatory locus, the X-inactivation centre (Xic).Recent … birds in the night comentarioWitrynaquences on the inactive X chromosome occurred after X-chromosome inactivation in development. These observations must be taken into account when considering the propagation of differential methylation as a mechanism for the propagation of imprinted infor mation in development (see Fig. 2).
