论文摘要
在熔化的过渡附近，弯曲弹性常数$κ$是双链DNA（dsDNA）的新兴特性，不得遵循小长度$ n $的杆状缩放。 $κ$与温度的降低是由连续过渡的变性气泡确定的，例如，当两条链为高斯时，但是通过Y型构型以y型构型的断开键，以进行一阶转换，以及具有排除体积相互作用的链。在后一种情况下，杠杆规则正在运行，尽管已知dsDNA是单个相，但仍意味着相共存。
Near the melting transition the bending elastic constant, $κ$, an emergent property of double-stranded DNA (dsDNA), is shown not to follow the rod-like scaling for small length $N$. The reduction in $κ$ with temperature is determined by the denatured bubbles for a continuous transition, e.g., when the two strands are gaussian, but by the broken bonds near the open end in a Y-like configuration for a first-order transition as for strands with excluded volume interactions. In the latter case, a lever rule is operational implying a phase coexistence although dsDNA is known to be a single phase.
