In the present era of genomics, there has been an explosion in the amount of information available about the DNA.DNA Microarrays or biochips are prominent among these new technologies. The use of microarrays for gene expression profiling, genotyping, detection of mutations and gene discovery are leading to remarkable insights into the function of thousands of genes previously known only by their sequence. The article briefly describes the generation and applications of DNA Microarrays.
