Abstract
The present invention provides improved methods for amplifying a nucleic acid molecule. Specifically, the invention involves replacing at least one nucleotide of an oligonucleotide with a deoxyinosine residue, so as to more equalize the efficiency with which that oligonucloetide and a second oligonucleotide hybridize to a target molecule, and then amplifying the target molecule using, for example, the polymerase chain reaction. Improved amplification results from the improvement in the relative hybridization efficiencies.
