<p>This invention relates generally to nucleic acid hybridization analysis. More specifically, a method for detecting a point mutation in a DNA strand is provided, which method uses, inter alia, a test nucleic acid strand complementary to a target DNA strand, said nucleic acid strand comprises a sufficient number of ribonucleotide residues that span the position of said point mutation to be detected to form a target DNA strand/test nucleic acid strand duplex and RNase H cleavage of said target DNA strand/test nucleic acid strand duplex. Kits and arrays for detecting a point mutation in a DNA strand comprising test nucleic acid strand comprising a sufficient number of ribonucleotide residues that span the position of said point mutation to be detected are also provided.</p> |
