You are studying a biochemical pathway in the mold neurospora where enzyme 1 converts the initial substrate into intermediate substrate a; enzyme 2 converts intermediate substrate a into intermediate substrate b; enzyme 3 converts intermediate substrate b into intermediate substrate c; and enzyme 4 converts intermediate substrate c into the end product, an amino acid that is essential for growth. you isolate a mutant that is unable to grow on minimal media. which data would provide the strongest support for the hypothesis that this mutation occurred in the gene that codes for enzyme 2?
a. the mold can grow on rich medium plus intermediate substrate c, but not on rich medium plus intermediate substrate b. b. the mold can grow on minimal medium plus intermediate substrate b, but not on minimal medium plus the initial substrate. c. the mold can grow on minimal medium plus intermediate substrate b, but not on minimal medium plus intermediate substrate a. d. the mold can grow on rich medium plus intermediate substrate d, but not on rich medium plus intermediate substrate c. e. the mold can grow on minimal medium plus intermediate substrate a, but not on minimal medium plus intermediate substrate c.
