Why Pentose- and Not Hexose-Nucleic Acids? Purine-Purine Pairing in homo-DNA: Guanine, Isoguanine, 2,6-Diaminopurine, and Xanthine

Article abstract of DOI:10.1002/hlca.19980810302

This paper concludes the series of reports in this journal [1-4] on the chemistry of homo-DNA, the constitutionally simplified model system of hexopyranosyl-(6′ → 4′)-oligonucleotide systems studied in our laboratory as potentially natural-nucleic-acid al
