Lambda-cl_gene Lac_gene TetR_gene 
This is a network model termed as Repressilator in which LacI inhibit transcription of tetR which in turn inhibit transcription of Lambda phage. This model simulates the result as per the Fig 1c of the paper : Elowitz MB, Leibler S., Nature. 2000 Jan 20;403(6767):335-8.
