Implementation

The model of the switch circuit has been implemented using the Simbiology Toolbox in MATLAB.

For the sake of simplicity, the effects of dimerization and dimerization/tetramerization of tetR and LacI/LacIIs have been neglected. So we did with the additional steps involving the RNApolymerase in the transcription of proteins and the ribosomes in the translation of proteins.
