base stacking

The results showed that the entire DNA molecule was damaged by acetic acid including backbone phosphodiester groups , deoxyribose and base stacking .

证明了乙酸对DNA的损伤是整个分子，包括骨架磷酸基团、脱氧核糖及碱基。

Detailed energy analysis indicated that the steric interaction in the process of the complex inserting to base stacking determined the recognition results and the electrostatic interaction made an effect in some extent .

详细的能量分析发现：在配合物插入碱基堆积过程中的空间位阻状况决定了识别作用的结果，静电相互作用也在一定程度上产生了影响。

Base mismatching could enhance the inhibitory effects of K + , suggesting that the effects of K + , were inter-related with the succession of base stacking in triplex DNA .

碱基的错配可使K~＋的抑制作用显著增强，提示K~＋的效应强弱可能与三链结构中碱基准积的连续程度有关。
