Structural biology is an interdisciplinary science which is mainly focused on the study of molecular structures and dynamics of biological macromolecules, the proteins, nucleic acids and how these alterations are occurred in their structures affecting their function. Structural biology incorporates the principles of molecular biology, biochemistry and biophysics regarding the molecular structure of biological macromolecules. It even provides information about the structural alterations and thus affecting their function. This process of determination of structures of proteins, nucleic acids takes years as the shape, size and assemblies of the molecules keep altering the function. The researchers and the biologists working on the functioning of the macromolecules have an immense interest in its studies.
