Apoptosis is a highly regulated process of programmed cell death that
culminates in the condensation of chromatin,the degradation of chromosomal DNA,
and eventual removal of damaged cells from a healthy organism. Caspases,
central regulators of the apoptotic program, are a conserved family of cysteine
acid proteases that exist as dormant zymogens until activated by an apoptotic
stimuli. This leads to a cascade of caspase cleavage, resulting in the eventual
proteolysis of key proteins involved in the regulation of cellular/nuclear
structure and the metabolism of DNA.
Caspase:
The 'c-' reflects the cysteine protease mechanism and the '-asp-ase' the
ability to cleave after aspartic acid.
However Caspase family expanded and enzyme activity changed far beyond the
description.

Assembly of histone proteins forms nucleosome. something take place in or on
nucleosome, so called intra...
