19 Claims

1. A method for sequencing a double-stranded nucleic acid molecule, comprising:

(a) preparing a sequencing library, wherein preparing a sequencing library comprises:

providing a set of hairpin adapters having a double-stranded region and a linker region;

ligating the hairpin adapters to a plurality of double-stranded nucleic acid molecules to generate a sequencing library comprising a plurality of adapter-nucleic acid molecule complexes; and

transitioning the adapter-nucleic acid molecule complexes from a double-stranded form to a linear single-stranded form, wherein each linear single-stranded adapter-nucleic acid molecule complex comprises at a first strand of a double-stranded nucleic acid molecule and a second strand of the same double-stranded nucleic acid molecule, separated by an adapter sequence;

(b) sequencing at least a portion of the linear single-stranded adapter-nucleic acid molecule complexes to obtain a plurality of sequence reads, wherein sequencing comprises cluster amplifying the portion of the linear single-stranded adapter-nucleic acid molecule complexes on a sequencing substrate;

(c) grouping the plurality of sequence reads into a plurality of families based at least in part by cluster on the sequencing substrate; and

(d) comparing sequence reads within a family to generate a consensus sequence for that family.
