What are the features of DNA Microarray?

DNA microarrays (or DNA chips) have been the most commonly used technique during the last two decades to globally monitor the cellular abundances of transcript species. A DNA microarray is a collection of microscopic DNA spots attached to a solid surface. Each DNA spot contains many thousands of copies of a specific DNA sequence, known as probes. These usually correspond to a short section of a gene generally at the 3′ end. Each microarray contains one or a few probe sets for each interrogated gene.
