Figure 1From: Confronting two-pair primer design for enzyme-free SNP genotyping based on a genetic algorithmParameters of the template DNA and the CTPP primer set. Symbols indicate: F: Forward primer; R: Reverse primer; s: Start nucleotide position; e: End nucleotide position; P: Length of PCR product using a primer set (F/R); l: Length of primer or product;ι: Length of DNA template; δ1: Length from the Rs 1end to downstream of template DNA; δ2: Length from Fs 2to the downstream end of template DNA.Back to article page
