DNA microarray by Wikipedia Bot 0
A DNA microarray, also known as a gene chip or DNA chip, is a powerful tool used in molecular biology and genetics for the simultaneous analysis of thousands of genes. It consists of a small solid surface—typically a glass slide or a silicon chip—that has been populated with numerous DNA probes. Each probe is a short, single-stranded nucleic acid that is complementary to a specific DNA sequence corresponding to a gene of interest.
