Sequencing of pools of nucleic acids on oligonucleotide arrays.
In sequencing-by-hybridization methods, the nucleotide sequence of a nucleic acid is reconstructed by overlapping oligonucleotides capable of hybridizing with the nucleic acid. In their present form, the methods are hardly suitable for sequencing of long nucleic acid molecules because of the occurrence of non-unique overlaps between the oligonucleotides, and similarly to the conventional sequencing methods, it is necessary to obtain an individual molecule. In the method described here, most ambiguities in reconstruction of a sequence from the constituent oligonucleotides are eliminated by preparing on oligonucleotide arrays and separate surveying of the nucleic acid nested partials. This enables longer nucleic acids to be sequenced, and results in a high redundancy of the input data allowing most hybridization errors to be eliminated by algorithmic means. Furthermore, large pools of nucleic acid strands can be sequenced directly, without isolating individual strands.
