Structural biology is a branch of molecular biology, biochemistry, and biophysics that focuses on the study of the molecular structure of biological macromolecules, particularly proteins, nucleic acids (like DNA and RNA), and complex assemblies they form. This field aims to understand the relationship between the structure of these biomolecules and their function in biological processes.
