Structural Biology is the branch of molecular biology that focuses on the molecular structure and dynamics of biological macromolecules, particularly proteins and nucleic acids. Molecular Modeling, a subset of Structural Biology, employs computational techniques to model or mimic the behavior of molecules. Together, these fields provide critical insights into the function, interaction, and design of biological molecules.
