Abstract

Re-sequencing, they identification of the specific variants in a sequence of interest compared with a known genomic sequence, is a ubiquitous task in today's biology. Universal arrays, which interrogate all possible oligonucleotides of a certain length in a target sequence, have been suggested for computationally determining a polynucleotide sequence from its oligonucleotide content. We present here new methods that use such arrays for re-sequencing. Our methods are applied to data obtained by the polymerase signaling assay, which arrays single-based primer extension reactions for either universal or partial arrays of pentanucleotides. The computational analysis uses the spectrum alignment algorithm, which is refined and enhanced here in order to overcome noise incurred by the use of such short primers. We present accurate resequencing results for both synthetic and amplified DNA molecules.
