Watson began his speech with an account of his most famous accomplishment, the discovery of the double helical structure of the DNA molecule...
Watson, who won the Nobel Prize for discovering the structure of DNA, spoke yesterday to about 1,000 students in the Science Center, with just as many watching on simulcast from nearby overflow rooms...
Looking back on his achievement, he seemed frustrated that he and partner Francis Crick did not discover DNA's structure earlier. "There was no reason, [we didn't find it earlier]. We were incompetent," he said...
...harnessing the crime-busting power of DNA is building up state databases, like the one that found Smith's rapist. Forty-three states now have such databases, and they are growing rapidly. Virginia's DNA bank, for example, currently has 190,000 samples, which have produced about 60 matches so far. Those successes are likely to increase rapidly as Virginia adds 8,000 DNA samples a month...
...next big step is linking the states' databases. The FBI has started providing states with free CODIS (combined DNA index system) software, which digitizes and compares DNA profiles. This has already produced some impressive results. After a series of rapes in Sarasota, Florida investigators entered DNA from the crime scene into the national system. The DNA turned out to match that of Mark Daigle, who had served time in Virginia six years earlier for burglary. Florida officials arrested Daigle, and last year he was convicted of rape...
