Spotted microarrays allow measurement of fluorescence intensities

corresponding to mRNA levels for each gene or feature.

a. Are intensity ratio measurements for low-abundance transcripts independent

of measurements for high-abundance transcripts when reversetranscribed

DNA from the same mRNA sample is used for the hybridization?

b. Is there a similar dependence or independence for transcripts whose abundance

is measured by SAGE?
