PHASE-PROTECTING REAGENT FLOW ORDERINGS FOR USE IN SEQUENCING-BY-SYNTHESIS

摘要

A system for nucleic acid sequencing includes a machine-readable memory and a processor configured to execute machine-readable instructions. The instructions, when executed by the processor, cause the system to expose template polynucleotide strands in a plurality of defined spaces of a sensor array to a series of flows of nucleotide species, the series comprising a sequence of random flows; and obtain, for each of the series of flows of nucleotide species, a signal indicative of how many nucleotide incorporations occurred for that particular flow to determine a predicted sequence of nucleotides corresponding to the template polynucleotide strands.
