Abstract
The present invention addresses compositions and methods for cleaving nucleic acids. The invention allows one to reliably detecting point mutations in long and short target regions of nucleic acids in a safe, non-labor intensive, and cost effective manner. The methods and compositions of the present invention allow for the use of various RNases, such as RNase A, RNase I and RNase T2, in the detection of mutations. The present invention also identifies reaction conditions that result in significant improvement in specific mismatch cleavage in the NIRCA.TM. assay.
