DNA microarray

[¦dē¦en¦ā ′mī·krō·ə‚rā]
(cell and molecular biology)
A microscopic spot containing identical single-stranded polymeric molecules of deoxyribonucleotides (DNAs), usually oligonucleotides or complementary DNAs, attached to a solid support (such as a membrane, a polymer, or glass) used to simultaneously analyze the expression levels of the corresponding genes.
