-Examine the simple metabolic pathway in Figure 14.1. If A, B, and C are all required for growth, a strain that is mutant for the gene-encoding enzyme 1 would be able to grow on which of the following media?

Question

Quizplus · Accepted Answer

Since the mutant strain lacks the ability to produce the enzyme that converts nutrient A into nutrient B, it will not be able to grow in minimal medium or minimal medium supplemented with nutrient A only. However, if nutrient B is added to the minimal medium, it can be taken up and used in the pathway to produce C, allowing for growth of the mutant strain.
