PoPS (the flow of RNA Polymerase molecules along DNA) means the current of gene expression. Our logic gates accept PoPS input signals, but we cannot input a PoPS signal directly. We decide to add something into our system as input signal, such as cheminal ligands and light. So a convertor must be built firstly to convert these signals to PoPS signals.

Design of PoPS converters

The figure above shows the basic structure of our input device. It functions to convert chemical signals to the PoPS (the flow of RNA Polymerase molecules along DNA) signals of lac repressor and CI, which are actually the wires of our system.
