To understand why 3′,5′-phosphodiester bond is ultimately chosen by the nature as the DNA structural framework,in this article,the energy of the phosphoric acid,2′-ribodesose,cytosine,as well as their compounds phosphoric acid-2′-ribodesose,2′-ribodesose-cytosine and phosphoric acid-2′-ribodesose-cytosine were calculated following thermodynamic method.
为了解大自然选择3′,5′-磷酸二酯键作为DNA结构骨架的必然性,从热力学角度模拟和计算了磷酸、2′-脱氧核糖、胞嘧啶及它们在不同位置结合形成的磷酸-2′-脱氧核糖、胞嘧啶-2′-脱氧核糖、磷酸-2′-脱氧核糖-胞嘧啶的能量,发现3′-磷酸-2′-脱氧核糖、5′-磷酸-2′-脱氧核糖、1′(-4-胞嘧啶)-2′-脱氧核糖、3′-磷酸-1′(-4-胞嘧啶)-2′-脱氧核糖、5′-磷酸-1′(-4-胞嘧啶)-2′-脱氧核糖的能量比其他相应形式结合物的能量低。
