The long genomic DNA molecules in eukaryotes are fragile and prone to entanglement, and must be tightly folded to fit into the micrometric dimensions of mitotic chromosomes. Histones transform the monotonous linear structure of double‐helical DNA i

Previous studies indicated that mitotic chromosome structure consists of many stacked layers formed by a mononucleosome sheet folded as a helicoid. This multilayer chromatin structure justifies the cylindrical shape of chromosomes and the transverse

Diverse experimental evidences, including atomic force microscopy and cryo-electron tomography results, suggest that the chromatin filament of each metaphase chromosome is self-organized into stacked thin layers oriented perpendicular to the chromoso

This perspective aims to identify the relationships between the structural and dynamic properties of chromosomes and the fundamental properties of soft-matter systems. Chromatin is condensed into metaphase chromosomes during mitosis. The resulting st

Experimental evidence indicates that the chromatin filament is self-organized into a multilayer planar structure that is densely stacked in metaphase and unstacked in interphase. This chromatin organization is unexpected, but it is shown that diverse

Early results showed the emanation of chromatin fibers from mitotic chromosomes and nuclei swollen with water. In contrast, under metaphase ionic conditions, it was found that chromatin from mitotic chromosomes is planar and forms multilayered plates

Cryo‐electron tomography and small‐angle X‐ray scattering were used to investigate the chromatin folding in metaphase chromosomes. The tomographic 3D reconstructions show that frozen‐hydrated chromatin emanated from chromosomes is planar and

In a previous study, we found that metaphase chromosomes are formed by thin plates, and here we have applied atomic force microscopy (AFM) and friction force measurements at the nanoscale (nanotribology) to analyze the properties of these planar stru
