Question

The Beadle and Tatum experiments were based on all of the following assumptions except that. Supplemented media permit growth of auxotrophic strains of Nourospora X-irradiation can induce mutations. Two strains of auxotrophic Nourospora that grow on minimal medium supplemented with biotin have mutations in the same gene auxotrophs fail to grow on minimal media In their first round of screening. Boodle and Tatum plated spores on minimal medium. The purpose of this screen was to. Identify which mutants were deficient in vitamin synthesis pathways and which were deficient in amino acid synthesis pathways determine which of the mutants generated were auxotrophic for thiamine. Determine whether any auxotrophic mutants had been generated eliminate all nonmutant Neurospora from the population
