Method of identifying a cognate nucleotide (i.e., the 'next correct nucleotide') for a primed template nucleic acid molecule. In some embodiments, an ordered or random array of primed target nucleic acids characterized by different cognate nucleotides can be evaluated using a single imaging step to identify different cognate nucleotides for a collection of different primed template nucleic acid molecules. An optional incorporation step can follow the identifying step. A polymerase different from the ones used in the binding and examination steps can be used to incorporate a nucleotide, such as a reversible terminator nucleotide, preliminary to identification of the next cognate nucleotide.

Method and system employing distinguishable polymerases for detecting ternary complexes and identifying cognate nucleotides

Provided are compositions, methods and systems for determining the sequence of a template nucleic acid using a polymerase-based, sequencing-by-binding procedure. An examination step involves monitoring the interaction between a polymerase and template nucleic acid in the presence of one or more nucleotides. Identity of the next correct nucleotide in the sequence is determined without incorporation of any nucleotide into the structure of the primer by formation of a phosphodiester bond. An optional incorporation step can be used after the examination step to extend the primer by one or more nucleotides, thereby incrementing the template nucleotides that can be examined in a subsequent examination step. The sequencing-by-binding procedure does not require the use of labeled nucleotides or polymerases, but optionally can employ these reagents.
