First, you expose Neurospora spores to X-rays, establish a culture from an irradiated spore, and then grow it on (1)a minimal medium plus vitamins, (2)a minimal medium plus amino acids, and (3)a minimal medium. Interpret your results if the fungus grows in all three media. Interpret your results if the fungus doesn't grow in any of the media.
