Abstract

The CD spectra of double-stranded (ds) DNA dispersion particles with the “re-entrant” cholesteric structures formed in poly(ethyleneglycol)-containing solutions are compared. The high osmotic pressure of the solvent results in the dense packing DNA molecules and alteration of their secondary structure as well as a disorder of molecules in quasinematic layers of dispersion particles. Under these conditions, it is impossible to connect the adjacent ds DNA molecules by specific cross-links (nanobridges).

“重入”扭曲相准线性层中DNA结构的无序性
比较了在含有聚乙二醇的溶液中形成的具有“凹入”胆甾醇结构的双链(ds)DNA分散颗粒的CD光谱。溶剂的高渗透压导致密集堆积的DNA分子及其二级结构的改变,以及分散颗粒的准向列层中分子的无序。在这些条件下,不可能通过特定的交联(纳米桥)连接相邻的ds-DNA分子。
