DNA双螺旋结构模型分子式:分子量:CAS号:性质:是由沃森(Watson)和克里克(Crick)提出的。该模型认为DNA的两条多核苷酸链缠绕同一中心轴以反向平行的右手螺旋方式盘旋,两链的磷酸与脱氧核糖位于螺旋外侧,碱基位于内侧,分别通过由胸腺嘧啶(T)与腺嘌呤(A)、胞嘧啶(C)与鸟嘌呤(G)碱基对形成的水平氢键相连,每10个碱基对形成一个螺距,高度为3.4纳米。生物体内的天然DNA几乎都以这种B-DNA形式存在,此外还有A-DNA和Z-DAN的结构形式。DNA双螺旋结构在生理状态下是很稳定的,其稳定性的主要因素是碱基堆积力、互补碱基对之间的氢键、离子键和范德华引力。DNA双螺旋结构模型的确立在分子生物学发展中具有划时代的贡献,极大推动了分子生物学和分子遗传学的发展。
