Generation and Enzymatic Amplification of High‐Density Functionalized DNA Double Strands

Up to eight modifications could be incorporated into a DNA heteroduplex (see picture) by introducing different sets of 2′-deoxynucleotide derivatives through DNA polymerase mediated primer extension. All four natural nucleobases in each strand were substituted with different base-modified analogues. PCR conditions are described that allow the direct amplification of fully functionalized DNA double strands.
