Question

Nutritional mutant strains were isolated from wild type Neurospora which responded to the addition of certain supplements in the culture medium by growth (+) or no growth (0). Given the following responses for single gene mutants, diagram a metabolic pathway (using arrows to show the direction of the pathway), which could exist in the wild type strain consistent with the data, indicating where the chain is blocked in each mutant strain (by placing the designation for the enzyme above the arrow).
