Pyrophosphatelinkages are important in extant biology and are hypothesized to have played a role in prebiotic chemistry and in the origination of oligonucleotides. Inspired by pyrophosphate as backbones of primordial oligomers, DNA oligomers with varying amounts of pyrophosphate inserts (ppDNA) were synthesized and investigated for their base‐pairing properties. As expected, pyrophosphate inserts
