Want your own personal genome sequenced? Researchers said they had found a faster and cheaper way to do it that would cost only about $2.2 million. George Church and colleagues at Harvard Medical School hope eventually to reduce the cost further to $1,000 per genome — the entire DNA code of a person, plant or other organism. Their new method, described in a report in the journal Science, bypasses the traditional gel-based technology for analyzing DNA and instead uses color-coded beads, a microscope and a camera. It is considerably cheaper than the current methods, which cost an estimated $20 million for a human genome.
