A DNA microarray is hybridized with fluorescently labeled reverse-transcribed DNA as described in the text, where the control mRNA (C) is labeled with a green fluorescent compound and the experimental mRNA (E) with a red fluorescent compound. Indicate what you can conclude about the relative levels of expression of a spot in the microarray that fluoresces:
(a) Red
(b) Green
(c) Yellow
(d) Orange
(e) Lime green
