Nuclei are dynamic structures that move through the mitotic cell cycle, are involved in differentiation, and divide and fuse during reproduction. The DNA contents of nuclei from different plants vary by 2500-fold. The design and structure of nuclei is, therefore, both flexible and versatile. Features relating to genome, chromosome, and maybe even gene localization during interphase are now emerging. At the chromosomal level, studies of scaffold associations and DNA sequence organization are indicating structures that impose nuclear architecture.
细胞核是动态结构，在有丝分裂细胞周期中移动，参与细胞分化，并在繁殖过程中进行分裂和融合。不同植物细胞核的DNA含量相差2500倍。因此，细胞核的设计和结构既灵活又多样。与基因组、染色体甚至间期基因定位相关的特征正在显现。在染色体水平上，对支架关联和DNA序列组织的研究表明了构成核结构的结构。
