V8: Cell cycle control

V8: Cell cycle control. Already simple genetic circuits can give rise to oscillations. E.g., a negative feedback loop X ? R ? ? X can yield oscillations (X activates R, which inhibits X, so that R goes down, so that X goes back up. . .).

Cell Cycle Control System

Cell Cycle Control System . Checkpoints stop the cycle until go-ahead signal is received. There are 3 checkpoints (G 1 , G 2 , & M) that must be passed before Mitosis is completed. . Molecules associated with the cell-cycle clock.
