1. A method of detecting the presence of nucleic acid sequences, comprising:

  • binding polymers of at least one oligonucleotide probe to a substrate wherein said polymeric probes are comprised of monomeric sequence units that are complementary to a target sequence which exists as a single copy within a region of a nucleotide sequence contained in a DNA test sample wherein said monomeric sequence units are selceted from the group consisting of Sequence I.D. Nos. 1-112;

    contacting said substrate to which said polymeric probes are bound with amplification products of said test DNA sample containing uncharacterized oligonucleotide sequences, wherein a reporter moiety has been incorporated, such that individual complementary sequences that are contained in the amplified test sample are able to anneal to any monomeric sequence that is contained in any polymeric probe bound to said substrate;

    washing said substrate to remove unannealed amplified DNA test sample from said substrate; and

    detecting the presence or absence of reporter moieties retained by said polymeric probes on said substrate.
