Here, we describe the much debated 3D architecture of the human and mouse genomes from the nucleosomal to the megabase pair level by a novel approach combining selective high-throughput high-resolution chromosomal interaction capture (T2C), polymer simulations, and scaling analysis of the 3D architecture and the DNA sequence. Results: The genome is compacted into a chromatin quasi-fibre with ~5 ± 1 nucleosomes/11 nm, folded into stable ~30–100 kbp loops forming stable loop aggregates/rosettes connected by similar sized linkers. Minor but significant variations in the architecture are seen between cell types and functional states. The architecture and the DNA sequence show very similar fine-structured multi-scaling behaviour confirming their co-evolution and the above. Conclusions: This architecture, its dynamics, and accessibility, balance stability and flexibility ensuring genome integrity and variation enabling gene expression/regulation by self-organization of (in)active units already in proximity. Our results agree with the heuristics of the field and allow “architectural sequencing” at a genome mechanics level to understand the inseparable systems genomic properties. date: 2016 publisher: BioMed Central id_scheme: DOI ppn_swb: 1655358073 own_urn: urn:nbn:de:bsz:16-heidok-224325 language: eng bibsort: KNOCHTOBIATHEDETAILE2016 full_text_status: public publication: Epigenetics & Chromatin volume: 9 number: 58 place_of_pub: London pagerange: 1-22 issn: 1756-8935 citation: Knoch, Tobias A. ; Wachsmuth, Malte ; Kepper, Nick ; Lesnussa, Michael ; Abuseiris, Anis ; Ali Imam, A.
