Question

Quizplus · Accepted Answer

The Ames test detects reverse mutations where a substance causes genetic mutations that convert auxotrophic bacteria (which cannot grow without a specific nutrient supplementation) back to prototrophic bacteria (which can grow without the specific nutrient supplementation). This is used to assess the mutagenic potential of chemical compounds.
