Abstract: Certain embodiments provide a method of sequencing that comprises: a) contacting, under hybridization conditions, a target genomic fragment with: i. a vector oligonucleotide comprising a binding site for a sequencing primer; and ii. a splint oligonucleotide that hybridizes to the vector oligonucleotide and to the nucleotide sequences at the ends of a target genomic fragment, to produce a circular nucleic acid; b) contacting the circular nucleic acid with a ligase, thereby ligating the ends of the vector oligonucleotide to the ends of the target genomic fragment to produce a circular DNA molecule; c) separating the circular DNA molecule from the splint oligonucleotide; and d) sequencing the target genomic fragment of the circular DNA molecule using the first sequencing primer.
