Based on the pheromone response pathway, why do you think this is true? A dig1 dig2 double mutant also exhibits invasive growth on solid media. What phenotype do you think you would see in a dig1 dig2 ste12 triple mutant? A-11 Six genes, each conferring the ability to use the sugar 3 4 5 6 7 3 4 5 6 7 Are these results derived from a complementation or from a recombination experiment? The a / a diploids from the experiment in part a are now induced to sporulate. Out of 400 spores examined from each a / a diploid, the numbers that were able to grow on minimal medium are scored here. 1 0 d. The biochemical pathway involved in the biosynthesis of sneezan is linear. One of the steps of the pathway is catalyzed by a heterodimeric enzyme, with each subunit encoded by a different gene. What is the biochemical pathway? Identify the genes that encode the enzyme involved in each step. Indicate which enzyme is dimeric. A-10 a. 3 19 3 5 100...
