In a former life I was a lab tech in a molecular biology lab- I wish that I had resources like this Cell Biology Animation site as a resource when I was learning about DNA replication, photosynthesis, and the citric acid cycle.
Applications for Science Teachers: This site has great animations with explanatory text that could visually support learners in high school biology, AP biology, and biotechnology classes. This would also be useful for college students learning about these molecular level processes.
