B)withdrawal from the cell cycle

Question

Quizplus · Accepted Answer

The MAP kinase cascade is involved in the cellular response to stress and can lead to the activation of downstream effectors that cause cells to withdraw from the cell cycle and enter a cell cycle arrest phase. This is a protective mechanism that allows cells to repair any damage before resuming cell division.
