On the 50th anniversary of the double helix structure of DNA, the goals of the Human Genome Project were officially completed. When started in 1990, it was projected to take 15 years and cost $3 billion. It actually took 13 years and $2.6 billion. This draft covers 99% of the genome and closed 99.5% of the gaps in the rough draft. The 24 April 2003 issue of Nature will lay out 15 grand challenges that will be taken on next, to build on this success.
