Between which two stages of the Neurospora life cycle do most mitotic cell divisions occur? b. Neurospora has an arginine amino acid synthesis pathway shown below: Suppose I have a neurospora strain that has a mutation such that it will not grow unless I supplement the media (food) with arginine (but not with citrulline or ornithine). What gene is mutated? Explain your reasoning. c. Suppose I take the strain above that only grows with arginine supplements and cross it to a different mutant Neurospora strain that grows with arginine and citrulline supplements but not ornithine supplements. Assming genes A, B and C are unlinked and there is only one mutation per strain: i) What percentage of the progeny will grow on ornithine? ii) What percentage on citrulline? iii) What percentage on arginine?
