For this homework, I reduced the larger project to a smaller and experimentally interpretable proof-of-concept genetic circuit. The current construct uses constitutive expression of rtTA3G together with a TRE3G-controlled XBP1s reporter cassette. Doxycycline provides an external timing input, allowing the production-associated module to be activated at a selected point during culture.Hugoen
