Single-input module

Definition

A single-input module is a basic component in synthetic biology that receives input from one source and produces a specific output based on that input. This type of module is essential for constructing complex biological circuits by allowing the integration of various signals and responses within a cell. Single-input modules serve as fundamental building blocks in the design of logic gates and network motifs, enabling precise control over cellular behavior.
