Biological physics is a multidisciplinary field that combines principles of physics with the study of biological systems. Researchers in this field use techniques and models from physics to understand the behavior, structure, and dynamics of biological systems at various scales - from molecules and cells to complex organisms. This field addresses questions related to biological processes, such as protein folding, DNA replication, cellular signaling, and the mechanics of cell movement. By applying physics principles to biological systems, researchers aim to uncover fundamental principles that govern life and contribute to advancements in fields such as medicine, biotechnology, and bioengineering.
