  1. An essential amino acid, D, is made from precursors A, B, and C by the following pathway: A B C D Several mutant bacteria are isolated that are unable to grow on minimal media. Each is tested on minimal media, as well as on minimal media plus chemicals A, B, C and D. Q1: Mutant 1 has lost the function of the gene encoding the enzyme required for the reaction of: A to B B to C C to D None of the above
