Which Molecule is Used for Hybridization to DNA Bound on a DNA

Question

Which molecule is used for hybridization to DNA bound on a DNA microarray?
A) DNA
B) RNA
C) mRNA
D) cDNA
E) qDNA

Accepted Answer

cDNA (complementary DNA) is created from mRNA through the process of reverse transcription. The cDNA is then used as the molecule for hybridization to the DNA probes on a DNA microarray. This allows for the detection of gene expression levels in a sample. DNA, RNA, mRNA and qDNA are not used for hybridization to DNA microarrays.
