Abstract
We describe a simple computation of the worm-like chain model and obtain the corresponding force-versus-extension curve. We propose an improvement to the Marko and Siggia interpolation formula of Bustamante et al (Science 1994, 265:1599-1600) that is useful for fitting experimental data. We apply it to the experimental elasticity curve of single DNA molecules. Finally, we present a tool to study the agreement between the worm-like chain model and experiments.
摘要
我们描述了蠕虫状链模型的一种简单计算方法，并得到了相应的力-伸长曲线。我们对Bustamante等人（《科学》，1994年，265卷：1599 - 1600页）的Marko和Siggia插值公式提出了一种改进方法，该方法有助于拟合实验数据。我们将其应用于单个DNA分子的实验弹性曲线。最后，我们展示了一种工具，用于研究蠕虫状链模型与实验之间的一致性。
