 #I would expect the spots to be red since Yap1p target genes allow for increased resistance to environmental stresses. Therefore, a depletion of glucose in the environment (i.e. an environmental stress) would induce more expression of these genes.
 #Deletion of TUP1 and YAP1 would result in a red spot on the microarray for Tup1p compared to a green spot (expression compared to repression) and a brighter red spot for Yap1p (indicating more expression).

 #The ratio is calculated by dividing one gene’s activity in cells gradually consuming all the available oxygen by its activity in control cells with unlimited oxygen. Therefore, Gene X goes from black to dim red to black to medium green. Gene Y goes from black to medium red to dim green to bright green. Finally, Gene Z goes from black to dim red and stays at dim red (in the order of 1 hour, 2 hour, 3 hour, and 4 hour, respectively).
 #Genes X and Y were transcribed similarly (had similar ratios).

 #At time 0, no/very little change has occurred in terms of expression or repression of the gene because the cells have just been exposed to the experimental growth conditions. Spots with equal expression and repression compared to the control sample appear yellow because red and green mix to make yellow.
 #TEF4 was repressed over the course of the experiment indicated by the green color. TEF4's change in expression was part of the cell's response to a reduction in available glucose. Glucose is the source of energy for cells and in the absence of glucose, actions that expend the cells energy (such as translation) may be limited.

+#The TCA cycle does not use glucose directly--glucose is converted into pyruvic acid. When glucose levels are low, pyruvic acid is modified and converted into acetyl-CoA, which then enters the TCA cycle.
 #These genes in the common pathway could all be induced or repressed by the same transcription factor (pg. 119).
