Cancers are groups of cells that divide rapidly and uncontrollably. Thus cancer cells A)are always in the G₀ phase. B)never enter the cell cycle. C)have a relatively short G₁ phase and ignore the G₁ and G₂ checkpoints. D)are stuck at the metaphase plate.

Question

Quizplus · Accepted Answer

Cancer cells have a short G₁ phase and usually ignore the G₁ and G₂ checkpoints, which normally ensure that the cell has replicated its DNA correctly before proceeding to mitosis. This allows cancer cells to divide rapidly and uncontrollably. They are not always in the G₀ phase and are not stuck at the metaphase plate.
