The diagram represents the cell cycle. When cells leave the cell cycle, they exit during G1 phase and then enter G0 phase, a resting period. Most normal cells can leave G0 phase and reenter the cell cycle at G1 phase before entering S phase. Cancer cells are different because they cannot enter G0 phase and are likely to do which of the following?

The diagram represents the cell cycle. When cells leave the cell cycle, they exit during G1 phase and then enter G0 phase, a resting period. Most normal cells can leave G0 phase and reenter the cell cycle at G1 phase before entering S phase. Cancer cells are different because they cannot enter G0 phase and are likely to do which of the following?

Mutate during G1 phase

Fail to complete S phase

Die after completing mitosis

Repeat cell cycle continuously

Answer 1

Cancer cells are characterized by their ability to divide uncontrollably and often do not respond to the regulatory mechanisms that normally control the cell cycle. Since they cannot enter G0 phase, they are more likely to:

Repeat the cell cycle continuously.

This means they can proceed through the cell cycle stages without the normal checks and balances, leading to rapid cell division and tumor growth.
