• Sommario/riassunto: This work looks at how genome stability depends on the complex interaction of predefined and environmentally induced genetic and epigenetic states. It describes various phenomena associated with the maintenance of genome stability, including genetic and epigenetic responses to various stresses in exposed cells and organisms.
