| Their work uncovered the mechanisms used by cells to repair damaged DNA - a fundamental process in living cells. | |
| The prize money of eight million Swedish kronor will be shared among the winners. | |
| ""It was a surprise. I know that over the years I've occasionally been considered for a prize, but so have hundreds of other people. I feel lucky and proud to be selected today," Tomas Lindahl, from the Francis Crick Institute in the UK, told journalists. | |
| Claes Gustafsson, from the Nobel Committee, said the recipients had "explained the processes at the molecular level that guard the integrity of our genomes". | |
| DNA is open to an onslaught of different phenomena which can generate defects in our genomes. | |
| UV radiation and molecules known as free radicals can cause damage. Furthermore, defects can arise when DNA is copied during cell division - a process that occurs millions of times each day in our bodies. | |
| "Cigarette smoke contains small reactive chemicals, which bind to the DNA and prevent it from being replicated properly - so they are mutagens. And once there is damage in the DNA this can cause diseases including cancer," said Prof Lindahl. | |
| But a host of molecular systems continuously monitor and repair our genetic information. The three new laureates mapped in detail how these mechanisms worked. | |
