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/TPGPCPG. REMARK 3 DUE TO DISORDER, THE TETRANUCLEOTIDE WAS CONSTRUCTED AS TPGPTPG/ REMARK 3 TPGPTPG IN WHICH THE C5 METHYL GROUP OF THYMINE WAS ASSIGNED REMARK 3 OCCUPANCY OF 1/6 AND N2 OF GUANINE WAS ASSIGNED OCCUPANCY OF 5/6.
