A biological network is a complex system of interconnected biological components, such as genes, proteins, and metabolites, that interact with each other to perform specific functions within a living organism. These networks help to regulate various biological processes, including metabolism, cell signaling, and gene expression, contributing to the overall health and functioning of the organism. Researchers often use computational tools to analyze biological networks, allowing them to visualize and understand the relationships between different components. This approach can lead to insights in fields like systems biology, genomics, and drug discovery, helping scientists identify potential targets for new therapies and treatments.
