During a microarray analysis, cDNAs made from normal cells are stained with a green fluor and cDNAs from abnormal cells are stained with a red fluor. Which of the following statements is true about the results of this experiment?
A) Red spots indicate genes that are under-expressed in abnormal cells.
B) Red spots indicate genes that are not expressed in abnormal cells.
C) Red spots indicate genes that are over-expressed in abnormal cells.
D) Red spots indicate genes that are over-expressed in normal cells.
E) Red spots indicate pseudogenes.
