TOKYO-- While the Human Genome Project races to finish a rough draft of the 3 billion bases in our DNA by next March, three sequencing teams are about to reach a different, potentially more significant milestone: a final draft of the first human chromosome. Sometime within the next week or two, the international consortium sequencing chromosome 22 will conclude that it has done everything possible to complete the sequence. As the team approaches that landmark, it is also setting precedents for those whose work on the rest of the human genome is scheduled to be finished by 2003, including a definition of what constitutes success.
