Abstract
We have successfully achieved efficient recognition of mismatched sites in double-stranded DNA through the formation of an invasion complex by using partially noncomplementary peptide nucleic acids (PNAs). Owing to mismatches between 2 PNAs used for invasion, the undesired PNA/PNA duplex, which inhibits invasion complex formation, was destabilized. This approach overcame an inherent challenge in PNA invasion, in particular, undesired PNA/PNA duplex formation resulting from PNA complementarity, thereby enhancing overall invasion efficiency.
