FIGURE 4.6. Comparison of Northern blots with DNA microarray
data. a) Results from four individual Northern blots examining four different
genes and measuring mRNA production over time, as indicated. b) Results
from a series of microarrays for the same four genes of interest. Note the color
scale on the bottom of b), where bright green indicates a 20-fold repression
and bright red indicates a 20-fold induction. Black indicates no change in
transcription (i.e., the merged microarray spot would have appeared yellow).
