Systems biology is a research area that focuses on studying biological systems as a whole rather than individual components. It aims to understand how different parts of a biological system interact with each other to give rise to complex biological processes. This interdisciplinary field combines techniques and concepts from biology, mathematics, computer science, and engineering to model and analyze biological networks and pathways. By taking a systems-level approach, researchers can gain insights into the underlying mechanisms of diseases, drug responses, and other biological phenomena. Ultimately, the goal of systems biology is to improve our understanding of living organisms and to develop new strategies for diagnosing and treating diseases.
