What happens after you apply the dna from the two samples to the dna microarray?

Answer:

Because two complementary strands of DNA can rejoin, the cDNA that is applied to the microarray will pair up, or hybridize, with the single-stranded DNA molecules that are stuck to the spots of the microarray

The DNA form piles of single stranded DNA molecules. Each spot on the micorarray represents a different gene.
