For each MET3pr strength value, the simulation statistics (mean Inline graphic standard deviation) are computed from 15 independent realizations. In each realization, eight pedigrees are generated. Each pedigree of cells is initiated by a single daughter (D) or mother (M) cell. Fitting error is defined as Inline graphic, where Inline graphic and Inline graphic are the statistical data points in simulations and experiments, respectively (Inline graphic: mean cycle time of mothers, Inline graphic: mean cycle time of daughters, Inline graphic: mean G1 duration of mothers, Inline graphic: mean G1 duration of daughters, Inline graphic: CV of cycle time among mothers, Inline graphic: CV of cycle time among daughters, Inline graphic: CV of G1 duration among mothers, Inline graphic: CV of G1 duration among daughters, and Inline graphic through Inline graphic denote the simulation values for the same statistics). MET3pr (MET3 promoter strength) is the transcription rate of MET3-CLN2 divided by the transcription rate from the native CLN2 copy. Since the native copy is regulated by SBF, we normalize the full transcription rate by the time-averaged SBF concentration (0.3) in the simulations with no forced CLN2 expression (cln3). The experimental time window Inline graphic min to Inline graphic min is used in these simulations. As the results indicate, the medium strength MET3pr mimics experimental conditions the best among the three strengths (comparison between the strengths made in the main text). The number of failed cycles (due to event execution errors listed in Table S9) normalized by the number of complete cycles is the cycle failure ratio. Matlab script to reproduce the mean and CV values (medium MET3pr strength) is provided as File C in File S1.
