#TEF4, or "translational elongation factor", was repressed, as the dot on the figure corresponded to bright green. The TEF4 could be reacting to the low amounts of glucose which provides energy to the cell. The TEF4 resorts to, according to Campbell, an energy saving mode therefore the genes were repressed.

*(Question 12, p. 120) What mechanism could the genome use to ensure genes for enzymes in a common pathway are induced or repressed simultaneously?
+
#The best mechanism a genome can use is a transcription factor to ensure genes for enzymes have a common induced or repressed pathway.
*(Question 13, p. 121) Consider a microarray experiment where cells deleted for the repressor TUP1 were subjected to the same experiment of a timecourse of glucose depletion where cells at t0 (plenty of glucose available) are labeled green and cells at later timepoints (glucose depleted) are labeled red. What color would you expect the spots that represented glucose-repressed genes to be in the later time points of this experiment?
+
#According to Campbell, TUP1 is responsible for the repression of glucose-repressed genes. Given this information I would expect the spots to be red, because the TUP1 and glucose would be depleted at said time period.
*(Question 14, p. 121) Consider a microarray experiment where cells that overexpress the transcription factor Yap1p were subjected to the same experiment of a timecourse of glucose depletion where cells at t0 (plenty of glucose available) are labeled green and cells at later timepoints (glucose depleted) are labeled red. What color would you expect the spots that represented Yap1p target genes to be in the later time points of this experiment?
+
#I would expect Yap1p to be colored red as it is "a transcription factor known to confer resistance to environmental stress"(121). During glucose depletion a cell in under stress, there Yap1p would increase expressed target genes and therefore be overly expressed and turn bright red.
*(Question 16, p. 121) Using the microarray data, how could you verify that you had truly deleted TUP1 or overexpressed YAP1 in the experiments described in questions 8 and 9?
+
#To see if TUP1 has been deleted you can look at the change in time and see the coloring of the dot. If TUP! has been deleted it will turn black and not light up at all. To see if YAP1 has been overexpressed you can see once the gene turns bright red it is most likely highly induced.

Discovery Questions

  1. Blairtransciptiongraph.png
    • Gene X: Hour 1: Black Hour 3: Dim Red Hour 5: Black Hour 9: Medium Green
    • Gene Y: Hour 1: Black Hour 3: Medium Red Hour 5: Dim Green Hour 9: Bright Green
    • Gene Z: Hour 1: Black Hour 3: Dim Red Hour 5: Dim Red Hour 9: Dim Red
  2. Gene X and Y were similar. Both had similar fold induction increase then deplete to 1:1 then proceed to fold repression.
    • The technical reason these spots come up yellow is that there are equal amounts of green and red dye and when mixed they create yellow.
    • The biological reason a majority were unchanged, i.e yellow, was because of the conditions that the experiment placed on the DNA slides.
  3. TEF4, or "translational elongation factor", was repressed, as the dot on the figure corresponded to bright green. The TEF4 could be reacting to the low amounts of glucose which provides energy to the cell. The TEF4 resorts to, according to Campbell, an energy saving mode therefore the genes were repressed.
  4. During high stress environments genes are repressed and induced according to their energy levels. Due to TCA being a energy metabolic gene, it becomes induced in order to make energy efficiently and effectively.
  5. The best mechanism a genome can use is a transcription factor to ensure genes for enzymes have a common induced or repressed pathway.
  6. According to Campbell, TUP1 is responsible for the repression of glucose-repressed genes. Given this information I would expect the spots to be red, because the TUP1 and glucose would be depleted at said time period.
  7. I would expect Yap1p to be colored red as it is "a transcription factor known to confer resistance to environmental stress"(121). During glucose depletion a cell in under stress, there Yap1p would increase expressed target genes and therefore be overly expressed and turn bright red.
  8. To see if TUP1 has been deleted you can look at the change in time and see the coloring of the dot. If TUP! has been deleted it will turn black and not light up at all. To see if YAP1 has been overexpressed you can see once the gene turns bright red it is most likely highly induced.
