Design Notes

The inverter system consists of lactose operon, CⅠprotein and λPR012. The LacI repressor is constitutively expressed which inhibits transcription from the pLac promoter in the absence of IPTG, thus λPR012 could be active. While the expression of the CI repressor can be induced by externally added IPTG and inhibited the transcription of λPR012, hence realizing the reversal of the function.

The source of dual inverter was almost from iGEM part.
