Figure 1From: Time delay induced transition of gene switch and stochastic resonance in a genetic transcriptional regulatory modelModel of genetic regulation with a positive autoregulatory feedback loop. The transcription factor activator (TF-A) activates transcription with a maximal rate k f when phosphorylated (P) and binds as a dimer to specific responsive-element DNA sequences (TF-REs). TF-A is degraded with rate k d and synthesized with rate R bas .Back to article page
