Which of these is the disintegration of a cell nucleus, which occurs on the death of the cell?
Karyolysis (from Greek κάρυον karyon—kernel, seed, or nucleus), and λύσις lysis from λύειν lyein, "to separate") is the complete dissolution of the chromatin of a dying cell due to the enzymatic degradation by endonucleases. The whole cell will eventually stain uniformly with eosin after karyolysis. It is usually associated with karyorrhexis and occurs mainly as a result of necrosis, while in apoptosis after karyorrhexis the nucleus usually dissolves into apoptotic bodies.

Oh dear I hadn't chosen the answer yet!

Darlene Davidson, I guess we're to believe disintegration is not disintegration.

The true answer is apoptosis.

belgasem goma, that's too general

Thank you Naked Kitty Slave.

So many of these arguments could be avoided by steering clear of Wikicrap. If you're going to submit a question about the sciences, why not use a science based source. I know this might include doing a bit more research, god forbid.
KARYOLYSIS: Irreversible cell death characterized by lysing of nucleus, due to action of DNAase and RNASE.
Compliments of sciencedirect.com. And holy pancakes, this question has a correct answer. How bout that!

Niko Hilje, not true. Apoptosis is programmed cell death. This is the disintegration of a cell's nucleus due to enzyme degradation, which is not a programmed process.
