Scientists vie to break junk DNA's secret code By Roger Highfield, Science Editor (Filed: 06/10/2003) Huge tracts of human DNA, previously written off as meaningless junk, have been found to contain a hitherto unrecognised "genetic grammar", making the language of our genes much more complex than previously thought. The discovery is of potentially huge significance, since it could lead to an entirely new explanation for certain diseases and symptoms. A race is now on among teams of scientists worldwide to investigate this cryptic code. While the genetic recipe of a human being is spelt out with three billion letters of...
