Patent ID: 10323275

Abstract:
Described is a method for sequencing a polynucleotide strand by sequencing by synthesis, the method including selecting a predetermined order of nucleotides to provide to a sequencing reaction, the order being selected to correlate with a predicted sequence for the polynucleotide strand; monitoring the reaction to detect incorporation of a nucleotide into a synthesized polynucleotide strand; wherein, in the event that nucleotide incorporation is detected, proceeding to provide the next nucleotide in the predetermined order. In the event that nucleotide incorporation is not detected, the predicted sequence for the polynucleotide strand may be revised and a new predetermined order of nucleotides selected, wherein the new predetermined order is selected to correlate with the revised predicted sequence. In this way, the sequencing reaction provides feedback to modify the order of nucleotides provided, thereby improving the efficiency of the sequencing reaction.
