Representative distribution for duration of cell cycle phases for the spring model. On average, the model predicts that the G1 phase is the longest phase of the cell cycle, accounting for ∼8.5 hours. The G1/S transition and S phase last for ∼4.8 hours and ∼3 hours, respectively. The G2/M phase lasts ∼3.6 hours and has the narrowest distribution. Lavg, mean phase duration; Lstd, duration standard deviation.
