Abstract
The present invention relates to compositions and methods for the detection and characterization of nucleic acid sequences and variations in nucleic acid sequences. The present invention relates to methods for forming a nucleic acid cleavage structure on a solid support and cleaving the nucleic acid cleavage structure in a site-specific manner. For example, in some embodiments, a 5′ nuclease activity from any of a variety of enzymes is used to cleave the target-dependent cleavage structure, thereby indicating the presence of specific nucleic acid sequences or specific variations thereof.

58. A method for cleaving multiple oligonucleotides comprising:
-
a) providing;
i. a plurality of first oligonucleotides attached to a solid support;
ii. a second oligonucleotide attached to said solid support; and
iii. a cleavage agent; and
b) exposing said solid support to said cleavage agent under conditions such that;
