Abstract: A double-stranded template nucleic acid molecule may comprise an adaptor, the adaptor comprising a mismatch portion. The mismatch portion may comprise a first mismatch sequence in a first strand and a second mismatch sequence that is not complementary to the first mismatch sequence in a second strand. When the double-stranded template nucleic acid molecule is amplified to generate a cluster of amplified strands, and the cluster sequenced to generate a sequencing read, the portion of the sequencing read corresponding to the mismatch portion may be analyzed to determine whether the cluster of amplified strands has derived from only one or both strands of the double-stranded template nucleic acid molecule. Disagreements at one or more loci in sequencing signals, base calls, or sequencing reads between the two strand derivatives in the cluster may be used to correct for sequencing error and improve sequencing accuracy.
