A model of the nucleosome core is proposed based on a topologically linear array of histones attached sequentially to DNA. The linear complex folds helically forming a spring-like particle. Different variants of the particle are discussed (cylindrical springs with and without histone-histone contacts between turns of the helix, solenoidal spring). The model is consistent with known data about the nucleosome structure. Histones H3 and H4 have a special role in the model which is related also to the superstructure of chromatin.
基于与DNA顺序连接的组蛋白拓扑线性阵列，提出了核小体核心模型。线性复合物螺旋折叠形成弹簧状颗粒。讨论了该颗粒的不同变体（螺旋各圈之间有和没有组蛋白-组蛋白接触的圆柱形弹簧、螺线管弹簧）。该模型与关于核小体结构的已知数据一致。组蛋白H3和H4在该模型中具有特殊作用，这也与染色质的超结构有关。
