    摘要： Provided herein are compositions, systems, methods, and kits for joining together the ends of one or more polynucleotides using at least one pair of blocking oligonucleotide adaptors. Blocking oligonucleotide adaptors can be used to reduce the formation of adaptor dimers or trimers (or higher-order concatemers) which can improve the yield of desirable polynucleotide-adaptor products in any recombinant nucleic acid workflow. Blocking oligonucleotide adaptors can comprise a double-stranded oligonucleotide adaptor (duplex) having an overhang cohesive portion that anneals with a blocking oligonucleotide which can be a separate single-stranded oligonucleotide. A blocking oligonucleotide, when annealed to an overhang portion, can prevent undesirable hybridization of the overhang portion to another nucleic acid, such as the overhang portion from another blocking oligonucleotide adaptor or a polynucleotide of interest.

    摘要： In some embodiments, methods for obtaining sequence information from a nucleic acid template linked to a support include hybridizing a first primer to a template strand linked to a support, sequencing a portion of the nucleic acid template, thereby forming an extended first primer product that is complementary to a portion of the nucleic acid template. In some embodiments, the method further includes introducing a nick into a portion of the template strand that is hybridized to the extended first primer product, degrading a portion of the template strand from the nick using a degrading agent, where a portion of the extended first primer remains hybridized to an undegraded portion of the template strand, and sequencing at least some of the single-stranded portion of the extended first primer by synthesis.
