Synthetic biology is the construction of artificial biological systems, such as programmable cells, using principles from engineering, electronics, computer science and computational biology. Using biological circuit, we can produce a new concentration gradient that has twice the frequency. If 1 is represented by a concentration of the chemical within the threshold, and a 0 is represented by a concentration outside the threshold, then we can represent any two digit binary number. Thus, we can differentiate separate regions at certain distances away from a point source. The focus of these...
