Mapping the 'dark matter' of human DNA

Although our knowledge of the human DNA is extensive, it is nowhere near complete. For instance, our knowledge of exactly which changes in our DNA are responsible for a certain disease is often insufficient. This is related to the fact that no two people have exactly the same DNA. Even the DNA molecules of identical twins have differences, which occur during their development and ageing. Some differences ensure that not everybody looks exactly alike, while others determine our susceptibility to …
