Network topology

Definition

Network topology refers to the arrangement or layout of various elements (links, nodes, etc.) in a network. It describes how different components of a biological system, such as cells or genes, are interconnected and interact with each other. Understanding network topology is crucial in developmental biology because it helps researchers model and analyze complex biological systems and their developmental processes.
