Final answer:
Cell division, specifically multiplication of cells, is normally under control through tight regulation mechanisms in healthy cells. Failures of cell cycle control can lead to uncontrolled cell growth and the development of cancer. The precise regulation of the cell cycle is critical for maintaining the health of organisms.
Step-by-step explanation:
Cell division, specifically multiplication of cells, is normally under control through tight regulation mechanisms in healthy cells. These mechanisms prevent excessive and unwanted cell division, which can lead to cancer. Failures of cell cycle control, caused by inherited genetic abnormalities or environmental damage to DNA, can result in uncontrolled cell growth and the development of cancer. The precise regulation of the cell cycle is critical for maintaining the health of organisms.
