A Gene Interaction Network is a visual representation of how different genes interact with each other within a biological system. These networks help researchers understand the complex relationships between genes, including how they influence various biological processes and traits. By mapping these interactions, scientists can identify key genes that may play significant roles in diseases or developmental processes. In a gene interaction network, nodes represent individual genes, while edges (lines) indicate interactions or relationships between them. This approach is useful in fields like genomics and systems biology, as it allows for the exploration of gene functions and the identification of potential targets for gene therapy or drug development.
