Introduction to Microarrays

• 6b.

gene x: 1.0 (Black), 2.2 (Dim Red), 1.0 (Black), .15 (Medium Green)
gene y: 1.0 (Black), 4.5 (Medium Red), .95 (Black), .05 (Bright Green)
gene z: 1.0 (Black), 1.5 (Dim Red), 2.0 (Dim Red), 2.0 (Dim Red)

• 7.

Gene X and Gene Y were transcribed similarly.

• 9.

At the first point, most of the genes have not been acted upon.  Since they have neither been repressed or induced, the mRNA quantity is normal.  The red and green 1:1 ration is thus represented by yellow.
