Researchers have uncovered a previously unknown surveillance mechanism, known as a DNA damage checkpoint, used by cells to monitor oxidatively damaged DNA. DNA repair takes place approximately 10,000 times per cell, per day, through processes that are still only partially understood because of their complexity, speed, and the difficulty of studying complex interactions within living cells.
