1. A method for obtaining sequence information from a nucleic acid, the method comprising the steps of:
- capturing target nucleic acids with a sequence-specific capture probe to produce a target/probe duplex;
isolating said target nucleic acids from said target/probe duplexes;
attaching said target nucleic acids to a surface such that at least a portion of said target nucleic acids are individually optically resolvable;
exposing said target nucleic acids to a nucleic acid primer capable of forming a target/primer duplex;
introducing a polymerase and at least one nucleotide species comprising an optically-detectable label under conditions sufficient for template-dependent nucleotide addition to said primer;
removing unincorporated nucleotide;
identifying nucleotide species incorporated into said primer, thereby obtaining sequence information from said target.

13. A method for obtaining sequence information from a selected nucleic acid, the method comprising the steps of:
-
capturing target nucleic acids with a sequence-specific capture probes to produce a plurality of target/probe duplexes; attaching members of said plurality of duplexes to a surface such that at least some members of said plurality of duplexes are individually optically resolvable; introducing a polymerase and at least one nucleotide species comprising an optically-detectable label under conditions sufficient for template-dependent nucleotide addition to said probe; removing unincorporated nucleotide; identifying nucleotide species incorporated into said probe, thereby obtaining sequence information from said target. - View Dependent Claims (14, 15, 16, 17)
