Methods of selectively cleaving DNA containing duplex nucleic acids in a complex nucleic acid mixture, as well as nuclease containing compositions for use therein, are provided. In the subject methods, a nuclease or composition thereof is employed to provide for selective cleavage of DNA containing duplex nucleic acids in a complex nucleic acid mixture. Also provided are novel duplex-stranded specific nucleases and nucleic acids encoding the same, where the subject nucleases are enzymes that, preferentially cleave deoxyribonucleic acid molecules in perfectly matched nucleic acid duplexes as compared to non-perfectly matched nucleic acid duplexes of the same length and/or single stranded nucleic acids. The subject methods and compositions for practicing the same find use in a variety of different applications, including, but not limited to, nucleic acid analyte detection applications, gene expression profiling applications, detection of nucleic acid variants including single nucleotide polymorphisms applications, preparation of subtracted and normalized nucleic acid libraries, etc. Finally, kits for use in practicing the subject methods are provided.
