The<unk>  <unk>  is a nucleic acid amplification technique. While the better-known PCR carries out the amplification by polymerizing nucleotides,<unk>  instead amplifies the nucleic acid used as the probe. For each of the two DNA strands, two partial probes are<unk> d to form the actual one; thus,<unk>  uses two enzymes: a DNA polymerase and a DNA<unk> . Each cycle results in a doubling of the target nucleic acid molecule. A key advantage of<unk>  is greater specificity as compared to PCR..
