(d) Researchers discovered a strain of C. Parvum that expresses a functional variation of the lactate dehydrogenase gene. A DNA sequence comparison showed that the variant differs from the normal sequence in the region that codes for the enzyme's allosteric site. Predict the effect of FX11 treatment on C. Parvum cells that express this variant of lactase dehydrogenase. Provide reasoning to support your prediction. Explain how gossypol and FX11 might be used as drugs to treat C. Parvum infections in humans without negatively affecting human cells.
