question 36

Essay

At several points in the cell cycle there are checkpoints that control the cell's passage from one phase to the next.If a cell receives a signal at each checkpoint,it continues to the next phase; if it does not receive the signal,the cell does not continue.For example,a growth factor may stimulate a cell to move from G₁ into S phase.If no growth factor is present,the cell cycle stops in G₁ and the cell does not divide.Predict what would happen to a cell and to a multicellular organism if there was a defect at the checkpoint and the cell continued through the cell cycle even in the absence of a signal.
