One application of addressable conjugation is computation. Here, individual cells of a culture are the switches, and triplets of cells perform binary logic. Because connected NAND logic gates can perform any computation tasks, we have initiated their construction.
In this design, riboregulators are the inputs that control the transfer of a riboregulator output. Only when both riboreegulator inputs are received is a lacI gene expressed. The LacI product then represses the activation of the sending system.
