X-Ray Scattering Studies of Human Genome Organization
The hierarchical organization of the chromatin fiber, the functional form of DNA in cells, has been extensively studied from a single nucleosome to the genome-wide scale [1,2]. Chromosome conformation capture techniques revealed a detailed static picture of the genome's 3D folded state inside the cell nucleus, revealing presence of loops, topologically associated domains, A/B compartments and chromosome territories [3–5]. However, the complementary microscopy study that is necessary to bridge the interaction frequency and physical distance for the complete 3D picture of genome organization is limited by the wavelength of visible light.
