    Under certain conditions, homopyrimidine oligonucleotides can bind to complementary homopurine sequences in homopurine-homopyrimidine segments of duplex DNA to form triple helical structures. Besides having biological implications in vivo, this property has been exploited in molecular biology applications. This approach is limited by a lack of knowledge about the recognition by the third strand of pyrimidine residues in Watson-Crick base pairs.
