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

Question

Quizplus · 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.
