It is a laboratory tool used to analyze large numbers of genes or proteins at one time.Microarray is a hybridization of a nucleic acid sample (target) to a very large set of oligonucleotide probes, which are attached to a solid support, to determine sequence or to detect variations in a gene sequence or expression or for gene mapping (MeSH).
Applications.
1.Gene expression analysis.
2.Gene variation analysis.
