Under different conditions, oligonucleotides can form several different DNA structures such as duplex, triplex and quadruplex. All these structures exhibit an obvious difference in their CD spectra. The common charact...
THE observation of the formation of triplex DNA opened a possibility to control gene expression. Since then vast applications on biology and novel approaches to therapeutics have been accumulated considerably. Novel a...

A third pyrimidine strand can bind the complementary purine strand of homopurinehomopyrimidine tracts of duplex DNA to form a local triplex structure. Recently investigations have indicated that triplex-forming-oligon...
Ⅰ. INTRODUCTIONIt is well established that the exciplex is an intermediate in some fluorescence quenching processes, and in many photochemical reactions and biological processes, and also a photogeneration carrier in...
