Detailed explanation-1: -Apoptosis occurs normally during development and aging and as a homeostatic mechanism to maintain cell populations in tissues. Apoptosis also occurs as a defense mechanism such as in immune reactions or when cells are damaged by disease or noxious agents (Norbury and Hickson, 2001).
Detailed explanation-2: -In adults, apoptosis is used to rid the body of cells that have been damaged beyond repair. Apoptosis also plays a role in preventing cancer. If apoptosis is for some reason prevented, it can lead to uncontrolled cell division and the subsequent development of a tumor.
Detailed explanation-3: -They typically die by a process called apoptosis, sometimes referred to as “cellular suicide”. Apoptosis helps to shape our organs and physical features before birth and rids the body of unneeded or damaged cells that could potentially cause harm.
Detailed explanation-4: -Apoptosis is a secondary response to DNA damage, with the biological goal of protecting a multicellular organism against a damaged cell. The p53-dependent transcription response can also trigger another secondary response to protect the organism, and this is to enforce the growth arrest of a damaged cell.
