They irradiated N. crassa cells and then grew the mutants only on arginine. They irradiated N. crassa cells, grew all the mutants on arginine, and then grew each mutant on medium containing a different intermediate. They irradiated N. crassa cells, grew the mutants on arginine, and then grew the mutants on medium containing only the precursor for arginine synthesis. They irradiated N. crassa cells and then grew the mutants only on the intermediate ornithine.
