What Berkeley microbiologist developed this  test, which is named for him?
In a standard test for the mutagenic strength of a chemical, a suspected mutagen is mixed with a culture of bacteria in a histidine-free medium, and rat liver extract is added to simulate biological effects. Ordinary bacteria die from lack of histidi  ne, but mutants are able to produce it, and so thrive. What Berkeley microbiologist developed this  test, which is named for him?
