Karyolysis
Karyolysis is the complete dissolution of the chromatin matter of a dying cell due to the activity of DNase. The whole cell will eventually stain uniformly with eosin after karyolysis. It is usually preceded by karyorrhexis and occurs mainly as a result of necrosis, while in apoptosis after karyorrhexis the nucleus usually dissolves into apoptotic bodies.[1]
