Figure 1.

Time series of model-gene activity. Time series of three randomly selected trajectories (numerical solutions of Eq. (19)), showing the measurements of gene expression levels in in-silico over-expression experiment. Gene expression levels were measured from time t₁ until t₂ for the steady state levels, and from time t₃ until t₄ for the effect of perturbation. At the time t_p one gene was over-expressed.
