拓扑电荷孤子参与DNA活动吗?

Do Topological Charge Solitons Participate in DNA Activity?

Ziv Hermon, Shay Caspi, Eshel Ben-Jacob

摘要:

我们提出了一种新的DNA分子的电磁模型,其中的P-键作为隧道结和H-键作为电容器。在模型中的过量电荷产生两个耦合的修改的sine-Gordon方程,其中承认拓扑孤子激发。我们研究了孤子的动力学,它们对DNA输运性质的影响,并评论了它们在DNA功能中的作用。我们提出了具体的实验,以测试我们的预测。

英文摘要:

We present a novel electromagnetic model of DNA molecules, in which the P-bonds act as tunnel junctions and the H-bonds as capacitors. Excess charge in the model gives rise to two coupled modified sine-Gordon equations, which admit topological solitonic excitations. We study the dynamics of the solitons, their effect on the DNA transport properties, and comment about their role in the DNA functioning. We propose specific experiments in order to test our predictions.
