Two neutron scattering methods, small-angle neutron scattering (SANS) and spin-echo SANS, are used to unambiguously identify the large-scale structure as being a logarithmic fractal with the correlation function γ(r) ∼ ln(r/ξ). The smaller-scale structural level is shown to be a volume fractal with dimension DF = 2.41. By definition, the volume fractal is self-similar at different scales, while the logarithmic fractal is hierarchically changed upon scaling. As a result, the logarithmic fractal is more compact than the volume fractal but still has a rather high surface area, which provides accessibility at all length scales. Apparently such bi-fractal chromatin organization is the result of an evolutionary process of optimizing the compactness and accessibility of gene packing. As they are in a water solution, the HeLa nuclei tend to agglomerate over time. The large-scale logarithmic fractal structure of chromatin provides the HeLa nucleus with the possibility of penetrating deeply into the adjacent nucleus during the agglomeration process. The interpenetration phenomenon of the HeLa nuclei shows that the chromatin-free space of one nucleus is not negligible but is as large as the volume occupied by chromatin itself. It is speculated that it is the logarithmic fractal architecture of chromatin that provides a comfortable compartment for this most important function of the cell. 000865919 536__ $$0G:(DE-HGF)POF3-6G15$$a6G15 - FRM II / MLZ (POF3-6G15)$$cPOF3-6G15$$fPOF III$$x0 000865919 536__ $$0G:(DE-HGF)POF3-6G4$$a6G4 - Jülich Centre for Neutron Research (JCNS) (POF3-623)$$cPOF3-623$$fPOF III$$x1 000865919 588__ $$aDataset connected to CrossRef 000865919 65027 $$0V:(DE-MLZ)SciArea-160$$2V:(DE-HGF)$$aBiology$$x0 000865919 65017 $$0V:(DE-MLZ)GC-130-2016$$2V:(DE-HGF)$$aHealth and Life$$x0 000865919 693__ $$0EXP:(DE-MLZ)KWS3-20140101$$1EXP:(DE-MLZ)FRMII-20140101$$5EXP:(DE-MLZ)KWS3-20140101$$6EXP:(DE-MLZ)NL3auS-20140101$$aForschungs-Neutronenquelle Heinz Maier-Leibnitz $$eKWS-3: Very small angle scattering diffractometer with focusing mirror$$fNL3auS$$x0 000865919 7001_ $$0P:(DE-HGF)0$$aFilatov, Mikhail V.$$b1 000865919 7001_ $$0P:(DE-HGF)0$$aPantina, Rimma A.$$b2 000865919 7001_ $$0P:(DE-HGF)0$$aVarfolomeeva, Elena Yu.$$b3 000865919 7001_ $$0P:(DE-HGF)0$$aBouwman, Wim G.$$b4 000865919 7001_ $$0P:(DE-HGF)0$$aDuif, Chris P.$$b5 000865919 7001_ $$0P:(DE-HGF)0$$aHonecker, Dirk$$b6 000865919 7001_ $$0P:(DE-Juel1)130893$$aPipich, Vitaliy$$b7$$ufzj 000865919 7001_ $$0P:(DE-HGF)0$$aGrigoriev, Sergey V.$$b8 000865919 773__ $$0PERI:(DE-600)2020879-0$$a10.1107/S160057671900921X$$gVol. 52, no. 4, p. 844 - 853$$n4$$p844 - 853$$tJournal of applied crystallography$$v52$$x1600-5767$$y2019 000865919 8564_ $$uhttps://juser.fz-juelich.de/record/865919/files/vg5110.pdf$$yOpenAccess 000865919 8564_ $$uhttps://juser.fz-juelich.de/record/865919/files/vg5110.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000865919 909CO $$ooai:juser.fz-juelich.de:865919$$pdnbdelivery$$pVDB$$pVDB:MLZ$$pdriver$$popen_access$$popenaire 000865919 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130893$$aForschungszentrum Jülich$$b7$$kFZJ 000865919 9131_ $$0G:(DE-HGF)POF3-6G15$$1G:(DE-HGF)POF3-6G0$$2G:(DE-HGF)POF3-600$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF3-6G15$$aDE-HGF$$bForschungsbereich Materie$$lGroßgeräte: Materie$$vFRM II / MLZ$$x0 000865919 9131_ $$0G:(DE-HGF)POF3-623$$1G:(DE-HGF)POF3-620$$2G:(DE-HGF)POF3-600$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF3-6G4$$aDE-HGF$$bForschungsbereich Materie$$lVon Materie zu Materialien und Leben$$vFacility topic: Neutrons for Research on Condensed Matter$$x1 000865919 9141_ $$y2019 000865919 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000865919 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search 000865919 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000865919 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000865919 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000865919 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000865919 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000865919 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000865919 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC 000865919 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bJ APPL CRYSTALLOGR : 2017 000865919 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000865919 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000865919 915__ $$0StatID:(DE-HGF)0320$$2StatID$$aDBCoverage$$bPubMed Central 000865919 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000865919 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List 000865919 920__ $$lyes 000865919 9201_ $$0I:(DE-Juel1)JCNS-FRM-II-20110218$$kJCNS-FRM-II$$lJCNS-FRM-II$$x0 000865919 9201_ $$0I:(DE-Juel1)JCNS-1-20110106$$kJCNS-1$$lNeutronenstreuung$$x1 000865919 9201_ $$0I:(DE-588b)4597118-3$$kMLZ$$lHeinz Maier-Leibnitz Zentrum$$x2 000865919 980__ $$ajournal 000865919 980__ $$aVDB 000865919 980__ $$aUNRESTRICTED 000865919 980__ $$aI:(DE-Juel1)JCNS-FRM-II-20110218 000865919 980__ $$aI:(DE-Juel1)JCNS-1-20110106 000865919 980__ $$aI:(DE-588b)4597118-3 000865919 9801_ $$aFullTexts
