The experiment known as one of the most beautiful experiments in biology changed the way we think about DNA. Learn about the experiment and the scientists who designed it—as well as the scientists who built on the results—with an online...

Scientists work every day to find solutions to genetic diseases. Scholars learn about the process of gene sequencing, mutations, and the results. They explore genetic diseases and therapies to intervene and help and, through case...

This simulation can be used to test how factors such as temperature, pH, and concentrations affect the reaction rates of two different enzymes in a biochemical pathway.

Learn about the critical role enzymes play in supporting life as you play games and solve puzzles, and do virtual experiments. Then take a quiz to check your understanding.
