genetic circuit

A genetic circuit is a collection of DNA segments designed to control cell behavior, similar to an electronic circuit controlling devices. These segments include genes and regulatory elements that work together to turn certain functions on or off in response to specific signals. By engineering genetic circuits, scientists can program cells to perform tasks like producing medicines, sensing environmental changes, or performing logical operations. Essentially, genetic circuits enable cells to process information and respond in a controlled, predictable manner, functioning as biological "software" within living organisms.
