<p>A nucleic acid base for hole transportation in DNAs which does not cause oxidative decomposition; and an artificial DNA molecule which can realize effective hole transportation in DNAs while maintaining the double spiral structure of the DNAs. Provided are: a nucleic acid which contains a benzodeazaadenine derivative base represented by the general formula (I): (I) (wherein R1, R2, R3, R4, R5, and R6 each independently represents hydrogen, amino, mono(lower alkyl)amino, di(lower alkyl)amino, hydroxy, lower alkoxy, halogeno, cyano, mercapto, lower alkylthio, or aryl; and R7 and R8 each independently represents hydrogen or a group bonded to phosphoric acid); and a polynucleotide comprising the nucleic acid.</p> |
