A bulky enzyme sidles up to a strand of DNA, locks on, and spits out a fresh ribbon of messenger RNA. A capsule of fat plows through a cell's membrane, emerging with a golden cap of grease. These are two of the chemical action flicks you can check out at this educational site. Creator James Hardy of the University of Akron in Ohio has directed about 100 short animations for beginning chemistry and biochemistry classes. Plenty of structure models let students study the twists and turns of molecules, from ethane to this buckyball. Other movies demonstrate lab techniques such as titration.
