The results obtained by electron microscopic observation show that the supercoiled pUC18 DNA adopts a doughnut-like solenoidal structure with outside diameter about 43.8 nm and inside diameter about 2.0 nm in ammonium acetate-H2O medium.

观察结果显示：在疏水性的甲酰胺-水展开系统中，DNA采取通常的互缠式结构；在含有1.5 mmol/L醋酸铵的水介质中制备的超螺旋DNA标本，DNA采取线圈型结构，测得pUC18 DNA分子这种结构的外直径约为43.8 nm，内直径约为2 nm。
