Fig. 21.

Plots showing the effect of varying parameter β₁ (all other parameters as per Table 1). The left plot shows the fraction of time the system spends oscillating with a period in the range 0–120 minutes, 120–300 minutes and 300–PE as β₁ is varied. The middle plot shows how the mean period varies as β₁ is varied. The right plot shows how the CV varies for mRNA and protein as β₁ is varied. As can be seen from the plots, varying β₁ has a large impact on the mean period. The plots show that increasing β₁ increases the mean period (Color figure online)
