Which is not true of cancer cells? a) cancer cells fail to undergo apoptosis. b) cancer cells exit the cell cycle and enter the g0 phase. c) cancer cells ignore signals that should cause them to stop dividing. d) cancer cells can migrate to other parts of the body through the process of metastasis.

The answer is; B

G0 is the stage of the cell cycle where the cells do not divide.

Cancer cells are renegade cells whose cell cycle regulation has failed, mostly due to damage in their genetic material, hence the cells proliferate unregulated.  The checkpoints in the stages of the cell cycle fail. An example is the failure of tumor suppressor genes that suppress the action of cyclins that promote the progression of the cell cycle.

B is correct

Cancer cells are characterized by unregulated cell growth, ignoring signals that would tell them to stop dividing. Cancer cells, instead will continue to divide, often many more times than a normal cell. Cancer cells also resist undergoing apoptosis or cell death. Cancer cells can travel to other areas of the body through the process of metastasis, often causing spread of the disease. Cancer cells WILL NOT exit the cell cycle to the G0 phase. The G0 phase is a non-dividing phase.
