My question: Explain the relationship between apoptosis and many forms of cancer. What are the prospects of using programmed cell death pathways as a targeted cancer treatment? My answer: Apoptosis is when it clears the body of cells that are set to have a limited life span and that are unneeded or dysfunctional. An example of this is when a woman is on her menstrual cycle; the cells lining the uterus are expelled from the body each month (Marieb and...
