DNA的“A”型和“B”型相变:自由能观点

Phase Transition between 'A' and 'B' forms of DNA: A Free Energy Perspective

Devashish Sanyal

摘要:

我们用群论方法研究了DNA从B型到A型的结构转变。该跃迁不是有序-无序型的,因此为了构造一个朗道型的跃迁理论,我们定义了一个更高的对称性和相关的序参量。我们还讨论了所有的构象的问题,实验观察到的过渡过程中,从根本上不同或没有。

英文摘要:

We study the structural transition from `B' form of DNA to 'A' form of DNA using group theoretic methods. The transition is not of the order-disorder type and hence to construct a Landau kind of theory for the transition we define a higher symmetry and relevant order parameters. We also discuss the issue of all the conformations, observed experimentally during the course of transition, being fundamentally different or not.
