DNA变性动力学模型的普适性

Models of DNA denaturation dynamics: universal properties

Marco Baiesi, Enrico Carlon

摘要:

我们简要回顾了一些用于描述DNA变性动力学的模型,重点是动力学指数$z$的值,它管理的缩放的特征时间$τ\sim L^z$作为序列长度$L$的函数。这些模型包含不同程度的简化,特别是有时它们不包括螺旋缠结的描述:我们讨论这方面如何影响$z$的值,范围从$z=0$到$z \approx 3.3$。还提到了与实验的联系。

英文摘要:

We briefly review some of the models used to describe DNA denaturation dynamics, focusing on the value of the dynamical exponent $z$, which governs the scaling of the characteristic time $τ\sim L^z$ as a function of the sequence length $L$. The models contain different degrees of simplifications, in particular sometimes they do not include a description for helical entanglement: we discuss how this aspect influences the value of $z$, which ranges from $z=0$ to $z \approx 3.3$. Connections with experiments are also mentioned.
