Spatial Organization of Chromosomes and the Role of DNA Tension

Two protein complexes are primarily responsible for chromosomal spatial organization in human cell nuclei. DNA tension has an unanticipated function in this. Together with Austrian colleagues, nanoscientist Cees Dekker and his PhD candidate Roman Barth of TU Delft’s Kavli Institute of Nanoscience published their detailed visualization in Nature on April 19th, 2023.
