This suite of dynamic tutorials explores the critical relationship between structure and function in biomolecules. The tutorials take advantage of the Chemscape Chime plug-in, which reads the atomic coordinates of molecules and renders them as interactive 3D images. New tutorials will be added all regularly, so check back often! Attention tutorial users!: Netscape Communicator (version 4.5 or above) and Chemscape Chime (plug-in version 2.0 or above) are required to view the tutorials.
