DNA MICROARRAY TECHNOLOGY One of the most exciting nucleic acid analysis techniques is microarrays or DNA chips. They provide a radically different approach to large-scale analysis and qualification of genes and gene expression patterns. A microarray consist of an ordered arrangement of hundreds or thousands of DNA sequences such as oligonucleotides or cDNAs deposited onto a solid surface approximately 1,2 x 1,2 cm. The microarray technique is based on hybridization of nucleic acids. Sequence complementarity provides the …
