Detailed explanation-1: -Definition. Apoptosis is the process of programmed cell death. It is used during early development to eliminate unwanted cells; for example, those between the fingers of a developing hand. In adults, apoptosis is used to rid the body of cells that have been damaged beyond repair.
Detailed explanation-2: -Apoptosis is the process of programmed cell death. It is used during early development to eliminate unwanted cells; for example, those between the fingers of a developing hand. 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.
Detailed explanation-3: -If cells are no longer needed, they commit suicide by activating an intracellular death program. This process is therefore called programmed cell death, although it is more commonly called apoptosis (from a Greek word meaning “falling off, ‘’ as leaves from a tree).
Detailed explanation-4: -Mitochondria are pivotal in the control of apoptosis, being involved not only in the intrinsic but also in the extrinsic pathway.
Detailed explanation-5: -Cell shrinks. Cell fragments. Cytoskeleton collapses. Nuclear envelope disassembles. Cells release apoptotic bodies. 28-Apr-2013
