WebCancer cells can divide many more times than this, largely because they express an enzyme called telomerase, which reverses the wearing down of chromosome ends that normally happens during each cell division ^4 4. Cancer cells are also different from normal cells in other ways that aren’t directly cell cycle-related. WebProgrammed cell death (PCD; sometimes referred to as cellular suicide) is the death of a cell as a result of events inside of a cell, such as apoptosis or autophagy. PCD is carried out in a biological process, which usually confers advantage during an organism's lifecycle.For example, the differentiation of fingers and toes in a developing human …
