Efficiency of sequencing by hybridization on oligonucleotide matrix supplemented by measurement of the distance between DNA segments.
DNA sequencing by hybridization on oligonucleotide microchip (SHOM) allows the determination of a spectrum of overlapping oligonucleotides constituting a DNA fragment that hybridizes to form perfect duplexes with an array of immobilized oligonucleotides and, as a result, enables reconstitution of the nucleotide sequence of the fragment. In longer DNA fragments, unambiguous reconstitution of DNA sequence is often impeded by the presence of repetitive regions and simple sequence repeats. Here it is demonstrated that SHOM supplemented by measurement of the distance between certain sites (for example, restriction sites or priming sites for PCR) within the analyzed DNA enables sequencing of much longer DNA fragments, containing repeats of different complexity.
