Explanation / Answer

Apoptosis is the process of programmed cell death during which a cell ages and is killed by its own lysosomes. Expression or activation of various apoptosis related genes trigger this death/killing process. If any one of the proteins is mutated and functionally inactive the cell death is stalled resulting in uncontrolled proliferation. This is one of the causes of cancer.
