Question
In Beadle and Tatum’s study of Neurospora, they were able to identify three classes of mutants that needed arginine added to minimal media in order to grow. The production of arginine includes the following steps:
precursor - ornithine - citrulline - arginine
What nutrient(s) could be supplied to allow for growth of the mutants with a defective enzyme for the ornithine - citrulline step? (Please look carefully at this experiment to answer)
What hypothesis does this work support? What does this hypothesis mean?
In addition to a protein, what other “gene products” can a gene code for (list all possibilities)?
