SCIENTISTS AND political leaders will celebrate today the final completion of the massive effort to decode the entire genetic sequence of the human genome - the recipe for every gene written in the language of the DNA molecule.
Two years ago, an international consortium of research-ers announced that they had finished the draft sequence of the "book of life", the three billion letters of DNA that make up the human genome.
They announced yesterday that they had finished the final, and in many ways most difficult, section of the sequencing effort covering some 30,000 genes and other assorted "junk" DNA that has no obvious function. Professor Allan Bradley, the director of the Wellcome Trust Sanger Institute in Hinxton, Cambridgeshire, which did nearly a third of the work, said: "Completing the human genome is a vital step on a long road but the eventual health benefits could be phenomenal. …
