Wild-Type Neurospora Was Treated with X Rays to Induce Heritable

Essay

Wild-type Neurospora was treated with X rays to induce heritable mutations.Treated Neurospora cultures were grown on minimal medium ("no addition" in the table) and minimal medium supplemented with the indicated compounds.Growth is indicated as dry weight of fungal material after 5 days.The table shows the results of three mutated strains that were linked to the metabolic pathway that generates arginine. Without arginine production, Neurospora cannot grow.Considering the biochemical pathway of arginine production and experimental outcomes shown, which two strains are represented by the double mutant? Explain the evidence for your answer and why the other combinations cannot be correct.
