How did Beadle and Tatum use genetic mutations in strains of Neurospora as an investigative tool?

    They crossed mutant strains that required a specific dietary supplement to survive with normal Neurospora.
    They showed that strains with a dietary supplement requirement were defective in one or another enzyme in the biochemical synthetic pathway for that supplement but never to more than one enzyme from the same biochemical pathway.
    They tested the hypothesis that a specific region of DNA (genes) could somehow encode a specific enzyme.
    all of the above
