1. A method for identifying a target nucleotide sequence comprising:

  • forming a ligation product on a target nucleotide sequence in a ligation detection reaction mixture, wherein the ligation product comprises an upstream primer portion and a downstream primer portion, wherein the upstream primer portion and the downstream primer portion are not complementary with the target nucleotide sequence;

    amplifying the ligation product to form an amplified ligation product in a polymerase chain reaction (PCR) mixture, wherein the PCR mixture comprises an upstream primer and a downstream primer; and

    detecting the amplified ligation product to identify the target nucleotide sequence.
