Biochemistry is all about study of metabolic pathways. Have you ever wondered how metabolic pathways are discovered. This video describes, how auxotrophs can be used to find intermediates of a metabolic pathway.
Collecting similar auxotrophs that requires specific metabolite for its growth and growing them side by side on a plate, is one of the classical method to find metabolic pathway.
