Definition

[Henderson's] hundreds to thousands of “spots” of different cDNAs or synthetic oligonucleotide probes, usually representing a selection of genes, arranged in a predetermined array on a glass microscope slide or other similar small-sized format. Microarrays are commonly used to measure the simultaneous expression of thousands of genes, by hybridization of the array with isolated cellular mRNA (or the cDNAs derived from it). They can also be used to detect single-nucleotide polymorphisms or other genomic features by hybridizing genomic DNA with an array of appropriate oligonucleotide probes. alt. DNA chip.
