Question

. Figure 1-7 shows a simplified pathway for arginine
synthesis in Neurospora. Suppose you have a special
strain of Neurospora that makes citrulline but not arginine. Which gene(s) are likely mutant or missing in
your special strain? You have a second strain of
Neurospora that makes neither citrulline nor arginine
but does make ornithine. Which gene(s) are mutant or
missing in this strain?
