In the microarray shown in your book, the cDNAs were labeled with red and green fluorescent tags
How then do you end up with spots on the microarray emitting yellow light?
a. In light, red and green are two of the primary colors, and the combination of the two will
produce yellow light.
b. The yellow light comes from the laser, and a yellow spot indicates that neither cDNA
hybridized to that spot on the microarray.
c. The over expression of one cDNA relative to the other will skew the color pattern of the
spot on the microarray. This result in the yellow color.
d. The color choice was an arbitrary decision by the artist and doesn't reflect how the process
actually works.
e. Yellow spots are those that contain no DNA probes on the chip.
