Two protein complexes carry the major responsibility for the spatial organization of chromosomes in our cell nuclei. DNA tension plays a surprising role in this. Nanoscientists now publish how they ...

Biology is never as straightforward as we learned in high school. Take sex-linked chromosomes as an example: we’re taught that biological males get XY chromosomes while biological females get two ...

It has been known for more than a century that the long DNA strands in cell nuclei are neatly folded into the characteristic shape of chromosomes, resembling bottlebrushes , in preparation for cell ...
