Checkpoint Definition

  • A checkpoint is a control point in the cell cycle where stop and go-ahead signals can regulate the cycle.

    Campbell Biology by J.B. Reece, L.A. Urry, M.L. Cain, S.A. Wasserman, P.V. Minorsky, R.B. Jackson

Checkpoint Explanation

A checkpoint is one of several points in the eukaryotic cell cycle at which the progression of a cell to the next stage in the cycle can be halted until conditions are favorable. One example of this is that if during the checkpoint its found that DNA has not duplicated or if the DNA is damaged and has not been repaired properly, the cell cycle will stop immediately and shall stay that way until the damage is repaired.
