Detailed explanation-1: -Why are disruptions to the cell cycle potentially dangerous to an organism? It could specialize the produced cells for a specific function. It could result in the production of abnormal or nonfunctional cells. Cells may exit the cell cycle and enter the G0 phase.
Detailed explanation-2: -Cancer is a disease that can occur when control of the cell cycle is lost.
Detailed explanation-3: -Cancer is the result of unchecked cell division caused by a breakdown of the mechanisms regulating the cell cycle. The loss of control begins with a change in the DNA sequence of a gene that codes for one of the regulatory molecules.
Detailed explanation-4: -Abnormal regulation of the cell cycle can lead to the over proliferation of cells and an accumulation of abnormal cell numbers. Cancer cells arise from one cell that becomes damaged, and when divided, the damage is passed on to the daughter cell and again to the granddaughter cells and so on.
