The Bacterial Traffic Light

The goal of our project is to construct an Eschericia coli bacterial "traffic light", that responds to increasing concentration levels of a given input (in our case, arabinose) with green, yellow, and red fluorescent outputs. Our project is unique because it is an analog biosensor, capable of responding to a continuous variable signal, rather than a binary biosensor that only signals on/off.

Sensors: This links to the pBAD promoters that sense the arabinose. Lock and Key: this controls when the colors are produced The Jammer: this mRNA sequence blocks the key from opening the lock.


The Traffic Light is composed of three distinct subparts:
