	2.	They have a defect in their G1 checkpoint so that they proceed to the S phase instead of staying in G1 (G0).
	3.	They are invasive, able to colonize other parts of the body by metastasis.
	4.	They have a defect in their cell cycle checkpoints so that they remain arrested in the G1 phase of the cell cycle.

Answer 1

The correct options are They exhibit uncontrolled cell division and They are invasive, able to colonize other parts of the body by metastasis.

Cancer cells are cells, which divide insistently and form tumours with abnormal cells. They continue to produce copies. They never differentiate. They continue to divide, cause more damage and invade new tissue which is result of other pro-survival characteristics specialized within cancer cells. The uncontrolled and rapid proliferation of cells, which lead to cancer. They are also able to spread from one part of the body to another in a process called as metastasis. They invade other organs and spread to distant locations or metastasis and become life-threatening.
