Uncontrolled State of mRNA and protein levels. (A) Uncontrolled state of mRNAs of lacl, tetR, cl in the tri-gene regulatory in a noise-free case. The initial states of computer simulation start from initial status as [3, 2, 1]. (B) Uncontrolled proteins cl, lacl, tetR in the tri-gene regulatory in a noise-free case. All states converge to 1.115 with in 50 second simulation time.
