The local structural organization of chromatin in mitotic chromosomes is not well understood. A new cryo‐electron tomography study from the Daban laboratory (Chicano , 2019) reveals that mitotic chromatin isolated from human cells can assume a plate‐like fine structure, containing layers of interdigitated nucleosomes. Such a multilayered organization suggests a possible model for mitotic chromatin compaction.
有丝分裂染色体中染色质的局部结构组织尚不清楚。Daban 实验室的一项新的冷冻电子断层扫描研究(Chicano,2019)表明,从人细胞中分离的有丝分裂染色质可以呈现出板状的精细结构,包含交错的核小体层。这种多层组织为有丝分裂染色质的压缩提供了一个可能的模型。
