Figure 6. The coefficient of variation (CV) versus mean number of (A) mRNA and (B) protein induced by varying transcription rate with different promoter transition rates.

The lines and discrete dots correspond to analytical results and MC simulations, respectively. The results with fast promoter transition rates are shown in blue dash-dotted line and , medium rates in red solid line and , and slow rates in magenta dashed line and ◊. The parameters here are the same as in Fig. 4 (A,C).
