(Phys.org) -- Repairing DNA breaks can save a cells lifebut shutting off the repair machinery can be just as critical. How cells accomplish this feat was unknown. However, new research by Johns Hopkins scientists, published in the February 22 issue of Nature, suggests that shutting down the repair machinery relies heavily on the same molecule used to start repair in the first place.
