question 156

Essay

Refer to the figure showing the steps used in microarray analysis to detect differences in expression between tumor tissue and normal tissue.The spots in the bottom panel represent individual genes for patients who have good prognoses (left) as well as for patients who have poor ones (right).The colors of those spots represent levels of expression: red = high expression, yellow = intermediate expression, green = low expression. Suppose one researcher said that she thinks a better prognosis would be associated with a general increase of expression of most of the genes examined.Is her hypothesis correct? Explain your answer.
