Medical Xpress / Map of tonsil's genetic 'spaghetti' yields insights into immunity

About 2 meters (6.6 feet) of genetic material must fit into the nucleus of each of most of our trillions of cells, coiling and winding to form what looks like a tangled mess. But when genes are used, how they are used and ...
