Design and characterisation of biological OR gates. a The genetic blueprint and logic output of three OR gate designs. Designs I and II are tandem promoters in opposite arrangement, while design III expresses RFP reporter in two distinct transcripts. Only design I and III are functional OR gates that generate RFP in the presence of either inputs. b Steady state profile of OR gate I for various concentrations of arabinose (input A) and rhamnose (input B). c Digital performance of OR gates at steady state. Error bars represent the standard deviation of three independent experiments
