1. A method for sequencing a target nucleic acid, comprising:
- (a) sequencing one or more bases of a target nucleic acid by extending a first sequencing primer hybridized to said target nucleic acid to generate a first primer extension product, thereby obtaining a first sequence read;
(b) releasing said first primer extension product from said target nucleic acid;
(c) hybridizing a second sequencing primer to said target nucleic acid;
(d) generating a second primer extension product by extending said second sequencing primer through limited extension without the use of labeled nucleotides;
(e) sequencing one or more bases of said target nucleic acid by further extending said second primer extension product to generate a third primer extension product, thereby obtaining a second sequence read; and
(f) determining a sequence of said target nucleic acid by assembling said first sequence read and said second sequence read.

21. A method for sequencing a target nucleic acid, comprising:
-
(a) sequencing one or more bases of a target nucleic acid by extending a first sequencing primer hybridized to said target nucleic acid to generate a first primer extension product, thereby obtaining a first sequence read; (b) releasing said first primer extension product from said target nucleic acid; (c) hybridizing a second sequencing primer to said target nucleic acid; (d) generating a second primer extension product by extending said second sequencing primer by a first number of nucleotides through limited extension without the use of labeled nucleotides; (e) sequencing one or more bases of said target nucleic acid by further extending said second primer extension product to generate a third primer extension product, thereby obtaining a second sequence read; (f) releasing said third primer extension product from said target nucleic acid; (g) hybridizing a third sequencing primer to said target nucleic acid; (h) generating a fourth primer extension product by extending said third sequencing primer by a second number of nucleotides through limited extension without the use of labeled nucleotides; (i) sequencing one or more bases of said target nucleic acid by further extending said fourth primer extension product to generate a fifth primer extension product, thereby obtaining a third sequence read; and (j) determining a sequence of said target nucleic acid by assembling said first sequence read, said second sequence read, and said third sequence read, wherein said first number of nucleotides is different from said second number of nucleotides. - View Dependent Claims (22, 24)
