Phillip McClean and Christina Johnson at North Dakota State University have produced some highly educational short movies that help to appreciate the connections between molecular structure, functional macromolecular assemblies, and the cell, as well as to understand the key principles of some biochemical processes. They are available free at http://vcell.ndsu.nodak.edu/animations/ These movies introduce proton gradients and ATP synthesis, cellular respiration (electron transport chain), protein transport (mitochondrial), transcription, mRNA processing, mRNA splicing, translation, and lac operon function. The movies are narrated with clear and nicely paced explanations, and component "players" are labeled. Molecules, complexes, and organelles are presented in schematic simplification, enabling the key points to be appreciated without being lost in unnecessary visual complexity. Each movie tells a story that integrates biochemical, genetic, and cellular processes. There are presently eight movies, each about three minutes in length. The movies are appropriate for grades 7-12, college, or post-graduate levels, having sufficient simplicity yet sufficient detail to intrigue viewers at all these levels. The movies play in Windows Media Player in both Windows and Mac OSX (Mac: http://www.microsoft.com/windows/windowsmedia/software/Macintosh/osx/default.aspx) Right click on the movie, then select Zoom, Full Screen. A link to these movies will be found in the K12 category under Virtual Cell Animation Collection at http://molvisindex.org ---- Eric Martz, Professor Emeritus, Dept Microbiology University of Massachusetts, Amherst MA US http://www.umass.edu/molvis/martz
