Systems biology is an interdisciplinary field that focuses on understanding complex biological systems by integrating data from various sources. It combines biology, computer science, engineering, and mathematics to analyze how different components of a biological system interact with each other. This approach helps researchers uncover the underlying mechanisms of cellular processes and disease. By using computational models and simulations, systems biology allows scientists to predict how changes in one part of a system can affect the whole. This holistic view is essential for developing new therapies and improving our understanding of genetics, metabolism, and cell signaling pathways.
