You identify an auxotroph that doesn't grow in normal medium, but does grow in medium supplemented with Q, indicating that it has a defect in one or more enzymes in this pathway. This auxotroph is also able to grow if you supplement the medium with D. Does this data support the one gene-one enzyme hypothesis? a yes, because only one enzyme is disrupted by the mutation b yes, because only one enzyme in the pathway is functional in the mutant strain c no, because multiple enzymes in the pathway could be functional in the mutant strain d no, because multiple enzymes could be disrupted by the mutation
