This site takes us into the world of structural biology -- a branch of molecular biology that focuses on the shape of nucleic acids and proteins (the molecules that do most of the work in our bodies). Learn about the structures and roles of proteins, tools used to study protein shapes, how proteins are used in designing new medications (for AIDS and arthritis), and what structural biology reveals about all life processes. Find out about careers in biomedical research.
