LINKED TARGET CAPTURE AND LIGATION
The invention generally relates to capturing, amplifying, and sequencing nucleic acids. In certain embodiments, linked capture probes and multiple binding and extension steps improve specificity over traditional single binding target capture techniques. Methods of seeding sequencing clusters with captured target nucleic acids are also disclosed. Linked adapters may be used to increase adapter ligation selectively or efficiency and yield. Ligation adapters and primers can be linked to various sequence-specific or feature-specific molecules to selectively bind targets for ligation or amplification with universal adapters or primers.

CONFORMATIONAL PROBES AND METHODS FOR SEQUENCING NUCLEIC ACIDS
This disclosure provides a method of determining a sequence of nucleotides for a nucleic acid template. The method can include the steps of contacting the nucleic acid template with a conformationally labeled polymerase and at least four different nucleotide species under conditions wherein the conformationally labeled polymerase catalyzes sequential addition of the nucleotide species to form a nucleic acid complement of the nucleic acid template, wherein the sequential addition of each different nucleotide species produces a conformational signal change from the conformationally labeled polymerase and wherein the rate or time duration for the conformational signal change is distinguishable for each different nucleotide species; detecting a series of changes in the signal from the conformationally labeled polymerase under the conditions; and determining the rates or time durations for the changes in the signal, thereby determining the sequence of nucleotides for the nucleic acid template.
