title: [Hybridase cleavage of RNA. V. Complementary precision of cleavage].
abstract: The efficiency of the cleavage of RNA involved in perfect as well as imperfect hybrid duplexes composed of three components: (1) homogeneous RNA's or polyribonucleotides; (2) corresponding complementary synthetic oligodeoxyribonucleotides; (3) E. coli RNase H was investigated. The predominant RNA hydrolysis was shown to take place within the perfect hybrid duplexes formed by the target RNA and the complementary oligodeoxyribonucleotide probes. RNase H was found to cleave effectively a number of imperfect hybrid duplexes containing a central base pair mismatch.
