Three levels of structural organization of eukaryotic DNA in the cell nucleus are considered in this paper: (i) the chain of nucleosomes; (ii) the solenoidal or superbead (nucleomere) model of compactization of the nucleosomal fiber; (iii) the mode of suprasolenoidal DNP-packing--loops or domains. Recent results bearing on the relation of these three levels to functional activity of chromatin are also discussed.
本文探讨了真核细胞细胞核中DNA的三个结构组织层次：（i）核小体链；（ii）核小体纤维压缩的螺线管或超珠（核粒）模型；（iii）超螺线管DNP堆积模式——环或结构域。还讨论了与染色质功能活性相关的这三个层次关系的最新研究结果。
