Exercise 17

ANALYZING DATA. You are repeating Beadle and Tatum's classic experiment in biology lab. 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.
