WHAT IS APAPTOSIS?
Apoptosis is the term used to describe the generally normal death of the cell in living organisms.It can occur because of signals inside the cell (intrinsic), or signals outside the cell (extrinsic). When it's caused by intrinsic signals, it may be the result of lack of sufficient nutrition to the cell or damage to the DNA in the nucleus. Extrinsic apoptosis may occur in response to a virus, or treatments like chemotherapy. Sometimes, a cell initiates the process in an attempt to fight a virus, like HIV.
