Phys.org / Immune cells selectively pull DNA from dying nuclei, revealing a process dubbed nucleocytosis

Over the years, cell biology has built a detailed picture of how cells compartmentalize their internal functions. Central to this organization is the nucleus, which houses the genetic material and is separated from the cytoplasm ...
