DNA三链结构模型和能力学研究

The Research on the DNA Three-stranded Structural Model and Energetics

本文按照用STM得到的一种变性DNA三链辫状结构图象,用分子建筑术分别构建了三链辫状结构和三链螺旋结构的分子模型。经过运用共轭梯度法优化后,作了能量分析,进而讨论了它们的稳定性和结构特征。

Based on the image of a denaturation DNA three-stranded braid structure obtained from STM, this paper presented respectively DNA three-stranded braid and tri-helix structure molecular models with molecular building. After doing the energy optimization using conjugated gradient method, we did the energy analysis, and then discussed the stability and structural features of DNA three-stranded braid and tri-helix structures.
