The course will introduce basic principles of protein and nucleic acids structures. The two most often used methods of macromolecular 3D structure determination, X-ray crystallography and nuclear magnetic resonance (NMR), will be discussed in detail. The course will be supplemented with visits to laboratories using these methods.
