    摘要: The present application provides polynucleotides comprising 5′-tails with sequence segments useful for the detection of target nucleic acid sequences, and methods for their use in detecting target nucleic acids. The polynucleotides are used to amplify a subsequence of a target nucleic acid in the presence of one or more ribonucleotides. The ribonucleotides are incorporated into amplification products at regular intervals complementary to the 5′-tail sequence segments. Cleavage of amplification products at the bond immediately 3′ to incorporated ribonucleotides produces detectably distinct fragments indicative of the presence or absence of a target nucleic acid.
