Inversing the natural hydrogen bonding rule to selectively amplify GC-rich ADAR-edited RNAs

Abstract excerpt

DNA complementarity is expressed by way of three hydrogen bonds for a G:C base pair and two for A:T. As a result, careful control of the denaturation temperature of PCR allows selective amplification of AT-rich alleles. Yet for the same reason, the converse is not possible, selective amplification of GC-rich alleles. Inosine (I) hydrogen bonds to cytosine by two hydrogen bonds while diaminopurine (D) forms three...
