Microarray:
DNA micro arrays are little more than glass microscope slides studded with a large number of DNA fragments, each containing a nucleotide sequence that serves as a probe for a specific gene.
Applications:
1.DNA micro arrays have been use to examine the change in gene expression ' signatures' of different types of human cancer cells.
2.It is used to monitor the gene expression of thousands of genes simultaneously, providing detailed, comprehensive shots of the dynamic patterns of gene expression that underlie complex cellular processes.
3.It is useful for predicting functions of the gene.
