核酸的分子静电势（I）──C－DNA的分子静电势

THE MOLECULAR ELECTROSTATIC POTENTIAL OF NUCLEIC ACIDS(I)──THE ELECTROSTATIC MOLECULAR POTENTIAL OF C-DNA

对于序列聚（ｄＧ－ｎｒ）和聚（ｄＡ－ｄＴ）来说，本文介始了Ｃ－ＤＮＡ活性位置的分子静电势（ＭｏｌｅｃｕｌｅｒＥｌｅｃｔｒｏｓｔａｔｉｃＰｏｔｅｎｔｉａｌ）的计算方法和结果［１］．描述了双螺旋表面外壳（ＳｕｒｆａｃｅＥｎｖｅｌｏｐｅｓ）上势的分布，并将其与Ｂ－ＤＮＡ有关结果［２－４］作了比较．

he molecular electrastatic potentials associocted with reactive site of C-DNA arecalculated for the sequences poly(dG-dC) and POly (dA-dT). The distribution of potential on thesurface envelopes of the doublehelices are also presented. The results are compared with those ob tained for B-DNA。
