Use this infоrmаtiоn fоr the next 2 questions: The аmino аcids phenylalanine and tryptophan are synthesized from several precursors as diagrammed below. Enzymes (Enz.) A through G are encoded by genes A through G, respectively. Auxotrophic mutants of the mold Neurospora have been identified that cannot make phenylalanine and/or tryptophan due to mutations in a gene (or genes) that encode the enzymes of this pathway. These two amino acids are necessary for life, so they must either be synthesized by the Neurospora cells or provided in the medium on which the yeast are grown. A Neurospora single mutant has been found that can make neither tryptophan nor phenylalanine. In which gene must the mutation be located?
