Methods and compositions are provided for detecting single nucleotide polymorphisms using a pair of oligonucleotides, a primer and a snp detection sequence, where the snp detection sequence hybridizes to the target DNA downstream from the primer and in the direction of primer extension. The snp detection sequence is characterized by having a nucleotide complementary to the snp and adjacent nucleotide complementary to adjacent nucleotides in the target and an electophoretic tag bonded to the 5′-nucleotide. The pair of oligonucleotides is combined with the target DNA under primer extension conditions, where the polymerase has 5′-3′ exonuclease activity. When the snp is present, the electophoretic tag is released from the snp detection sequence, and can be detected by electrophoresis as indicative of the presence of the snp in the target DNA.
