THE mitotic cell cycle is an orderly sequence of events, leading to cell division. In mammalian cell lines, a single event in the cycle exhibits first-order kinetics1, apparently dividing a cell's lifespan into a probabilistic state and a deterministic phase, termed A and B respectively. This rate-limiting event occurs during the G1 phase2,3, but its relation to the resting state and to the initiation of the cell cycle is unclear. In this paper we suggest that a probabilistic event exists in… CONTINUE READING
