genetic circuits

Genetic circuits are specialized arrangements of genes within a cell that function like electronic circuits, processing signals and controlling biological activities. They use natural or engineered DNA components to detect specific inputs—such as environmental changes or molecules—and produce desired responses, like producing a protein or turning genes on or off. Think of them as the cell’s programming system, enabling precise regulation and complex behaviors similar to electronic devices, but operating within living cells. This technology allows scientists to modify or create new cellular functions for applications in medicine, biotechnology, and research.
