WOBURN, Mass. - It's been three years since scientists completed a rough draft of the human genetic code, but nobody's rushing out yet for a personal DNA analysis. That's because the first draft took 12 years and cost billions of dollars. Today, the cost has fallen, but only to around $50 million. The target price is orders of magnitude away: $1,000 for an individual's DNA sequence. That's the price considered essential for giving scientists the thousands of sequenced samples they need to understand how genes work, and giving patients access to a personalized DNA snapshot at the doctor's office that could show the diseases they are at risk of developing. Some scientists believe the old methods of sequencing DNA, though improving, will never produce a $1,000 genome, and they are exploring radically different ways to map the blueprint of human life.
