In this animation produced by WGBH and Digizyme, Inc., learn how researchers expand a population of transformed bacterial cells using solid and liquid culture media. The animation explains the role of ampicillin (an antibiotic) and arabinose (a sugar), which are used for selection in the growth media. It also demonstrates how the transformed bacteria are separated from nontransformed bacteria.
