Sweden's Tomas Lindahl, American Paul Modrich and Turkish-born Aziz Sancar won the 2015 Nobel Prize for Chemistry for work on mapping how cells repair damaged DNA, giving insight into cancer treatments, the award-giving body said on Wednesday. "Their work has provided fundamental knowledge of how a living cell functions and is, for instance, used for the development of new cancer treatments," the Royal Swedish Academy of Sciences said in a statement awarding the 8 million Swedish crowns ($969,000) Thousands of spontaneous changes to a cell's genome occur on a daily basis while radiation, free radicals and carcinogenic substances can also damage DNA. To keep genetic materials from disintegrating, a range of molecular systems monitor and repair DNA, in processes that the three award-winning scientists all helped map out, opening the door to applications such as new cancer treatments.
