Transforming Bacteria

In this animation produced by WGBH and Digizyme, Inc., learn about bacterial transformation, the process by which DNA plasmids are introduced into a bacterial cell’s genome. The animation presents the physical challenges of getting the plasmids through the cell’s plasma membrane and the “heat shock” technique used to overcome them. It also shows how researchers test for successful transformations using experimental and negative control plates.
