Methods and compositions for the detection and quantification of nucleic acids are provided. In certain embodiments, methods involve the use of cleavable probes that comprise a ribonucleotide position that is susceptible to endoribonuclease (e.g., RNase H) cleavage in the presence of target nucleic acid molecules. Probes of the embodiments may also comprise non-natural nucleotide linked to a reporter and/or quenching moiety.

The present invention is directed methods for identifying, in a sample, one or more target nucleotide sequences differing from other nucleotide sequences in the sample by one or more nucleotides, one or more copy numbers, one or more transcript sequences, and/or one or more methylated residues, using ligation detection reactions, polymerase mediated extension reactions, and/or cleavage reactions. The present invention is also directed to methods for identifying, in a sample, one or more nucleotides in a target nucleotide sequence.
