(19), FORCE FIELD. THIS FORCE FIELD WAS REMARK 3 MODIFIED TO INCLUDE PARAMETERIZATION OF THIOG, AS DESCRIBED REMARK 3 ABOVE. STARTING STRUCTURES WERE ENERGY MINIMIZED BY 160 STEPS OF REMARK 3 POWELLS CONJUGATE GRADIENT MINIMIZATION FOLLOWED BY RMD WHILE REMARK 3 HEATING TO 600 K AT 50 K SEC-1, COOLING TO 300 K AT 25 K SEC-1, REMARK 3 AND EQUILIBRATING AT 293 K OVER 250 PS.

REMARK 210 SINGLE-STRANDED DNA MOLECULES REMARK 210 WERE PURIFIED USING ANION REMARK 210 EXCHANGE CHROMATOGRAPHY (MONOQ REMARK 210 HR 5/5, PHARMACIA BIOTECH). REMARK 210 PURITY WAS CONFIRMED BY UV REMARK 210 SPECTROSCOPY, ANALYTICAL ANION REMARK 210 EXCHANGE CHROMATOGRAPHY, AND REMARK 210 MASS SPECTROMETRY. THE GC AND REMARK 210 THIOGC DNA DUPLEXES WERE EACH REMARK 210 PREPARED BY ANNEALING EITHER REMARK 210 EQUIMOLAR AMOUNTS OF REMARK 210 COMPLIMENTARY STRANDS OR A 1.2 REMARK 210 MOLAR EXCESS OF THE UNMODIFIED REMARK 210 STRAND TO THE MODIFIED STRAND IN REMARK 210 BUFFER A (10 MM SODIUM PHOSPHATE, REMARK 210 50 MM NACL, PH 7.0) AT 70 C FOR REMARK 210 5 MIN., FOLLOWED BY SLOW COOLING REMARK 210 OVER 12 HOURS TO ROOM REMARK 210 TEMPERATURE.
