E. co Lisa Simplified Project Overview
 |
Each engineered cell (blue capsule) has genes (green box with arrow) for a light sensing protein (green oval) |
The light sensor is activated by passing the beam from a laser pointer over the petri plate |
 |
 |
The light sensor controls another gene (red box with arrow), for the protein agarase (red circles). Once activated by the laser pointer, the light sensor activates the agarase gene. |
Agarase breaks down the jello-like matrix that the cells rest on. When many cells produce agarase a depression becomes visible on the petri plate. |
