This site produced by the Dolan DNA Learning Center of the Cold Springs Harbor Laboratory contains a number of high quality animations that explain processes important in bioanalytical chemistry. For example, one animation illustrates the process of Sanger sequencing and another explains what Gene Chips are and how they work. PCR, gel electrophoresis, cloning, model organisms and stem cell lines are also treated. The site allows the animations to be viewed or downloaded for PC or Mac, which means that they can be easily incorporated into lectures.
