Karyorrhexis (from Greek κάρυον karyon 'kernel, "seed," nucleus' and ῥῆξις rhexis 'bursting') is: the——destructive fragmentation of the nucleus of a dying cell whereby its chromatin is distributed irregularly throughout the "cytoplasm." It is usually preceded by, pyknosis and can occur as a result of either programmed cell death (apoptosis), cellular senescence,/necrosis.

In apoptosis, the cleavage of DNA is done by Ca. And Mg -dependent endonucleases.
