Abstract

Small molecule-DNA hybrids with only two parallel DNA duplexes (rSMDH2) displayed sharper melting profiles compared to unmodified DNA duplexes, consistent with predictions from neighboring-duplex theory. Using adjusted thermodynamic parameters obtained from a coarse-grain dynamic simulation, the experimental data fit well to an analytical model.

摘要

仅含有两条平行 DNA 双链的小分子-DNA 杂交物（rSMDH2）与未经修饰的 DNA 双链相比，具有更陡峭的熔解曲线，这与相邻双链理论的预测一致。使用粗粒动力学模拟得到的调整热力学参数，实验数据很好地符合分析模型。
