  • Patent number: 5516641
    Abstract: A kit is disclosed for a method for detecting the presence of a target polynucleotide sequence. The kit comprises a first polynucleotide sequence and a second polynucleotide sequence complementary to non-contiguous portions of a target polynucleotide sequence, which first and second sequences are covalently attached when they are hybridized to the target sequence. The presence of the covalently attached first and second sequences is related to the presence of the target polynucleotide sequence. The invention may be applied to target polynucleotide sequences in DNA or RNA. Specific target polynucleotide sequences of interest will frequently be characteristic of particular microorganisms, viruses, viroids, or genetic characteristics, including genetic abnormalities.
