Abstract
Apoptosis (or cell-death) is a form of programmed cell death (PCD) or cellular suicide that occurs in multicellular organisms. The apoptosis is different from necrosis, in which cells die due to injury. The biochemical events lead to characteristic cell changes and death. These changes include blebbing, cell shrinkage, nuclear fragmentation, chromatin condensation, chromosomal DNA fragmentation, and global mRNA decay. The apoptosis produces cell fragments called apoptotic bodies that phagocytic cells are able to engulf and remove before the contents of the cell can spill out onto surrounding cells and cause damage to them. The Apoptosis is an orderly process in which the cell’s contents are packaged into small packets of membrane for garbage collection by immune cells.
