Structures for Molecular Biology

The table lists some of the molecules and complexes that are described in the readings for Molecular Biology courses. Interactive images of these structures can be viewed by following the links indicated under Description. The Reference column is the literature citation (and PubMed link) for the paper that describes each structure. See Viewing Tips below, for pointers on how to manipulate the linked Chime images.
