Apoptosis (from Ancient Greek á¼ÏÏÏÏÏÏÎ¹Ï falling off) is a process of programmed cell death that occurs in multicellular organisms. Biochemical events lead to characteristic cell changes (morphology) and death. These changes include blebbing, cell shrinkage, nuclear fragmentation, chromatin condensation, chromosomal DNA fragmentation, and global mRNA decay. Between 50 and 70 billion cells die each day due to apoptosis in the average human adult.
Diagram showing different responses of normal and cancer cells to conditions that would typically trigger apoptosis. 1  A normal cell with unfixable DNA damaged will undergo apoptosis. 2  A cancer cell with unfixable DNA damage will not undergo apoptosis and will instead continue dividing.
