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;
melting said target/probe duplex to release said target nucleic acids;
annealing a primer to the target nucleic acids to produce a target/primer duplex;
attaching said target/primer duplex to a surface such that at least a portion of said target/primer duplex is 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;
removing unincorporated nucleotide; and
identifying nucleotide species incorporated into the extended primer, thereby obtaining sequence information from said target.
