Passivation is the treatment of the surface of stainless steels, often with acid solutions (or pastes), to remove contaminants and promote the formation of the passive film on a freshly created surface (e.g. through grinding, machining or mechanical damage).
X inactivation is a process by which one of the copies of the X chromosome present in the female mammals is inactivated. The inactivated X chromosome condenses into a compact structure called as the he Barr body. Unlike the gene poor Y chromosome , the X chromosome contains over 1000 genes, that are essential for proper development and cell viability. Females carry two copies of X chromosomes , resulting in a double dose of X linked genes. To correct this imbalance mammalian females have evolved the unique mechanism of X chromosome inactivation. Transcriptionally silent Barr bodies maintain gene equality between makes ( XY ) and females ( XX ) .
