THE STRUCTURE HAS STATISTICAL DIS-ORDER AND THE REMARK 3 ASYMMETRIC UNIT CONTAINS A TETRAMERIC DUPLEX WHICH COULD STAND REMARK 3 FOR EITHER CPGPCPG/CPGPCPG OR CPAPCPG/CPGPTPG OR CPGPCPA/ REMARK 3 TPGPCPG. DUE TO DISORDER, THE TETRANUCLEOTIDE WAS CONSTRUCTED AS REMARK 3 TPGPTPG/TPGPTPG IN WHICH THE C5 METHYL GROUP OF THYMINE WAS REMARK 3 ASSIGNED OCCUPANCY OF 1/6 AND N2 OF GUANINE WAS ASSIGNED REMARK 3 OCCUPANCY OF 5/6.
