Abstract

A method for sequencing a polynucleotide strand by using sequencing-by-synthesis techniques. To address the problem of incomplete extension (IE) and/or carry forward (CF) errors that can occur in sequencing-by-synthesis reactions, an alternative flow ordering of dNTPs is used. In contrast to conventional flow orderings, the dNTPs are flowed in an ordering that is not a continuous repeat of an ordering of the four different dNTPs. This alternate flow ordering may reduce the loss of phasic synchrony in the population of template polynucleotide strands that result from IE and/or CF errors.
