This week, for example, scientists will describe the progress they have made tracking down genes that put people at risk for Alzheimer's disease. They will present fresh evidence that other factors--high-fat diets, for instance--may substantially elevate that risk. And most exciting of all, they will discuss...
JOUSTING FOR GENES
Until then, Venter had been randomly sampling and sequencing small bits of cDNA. But one of his new recruits, Hamilton Smith, a Nobelist from Johns Hopkins', proposed a bolder approach: "shotgunning" the entire genome of an organism. The idea was dramatically simple. Using an ordinary kitchen blender, they would shatter...
Venter first targeted the genome of an old laboratory favorite, the fruit fly, Drosophila melanogaster, whose genes have many counterparts in humans. By March he had succeeded in sequencing its genome--work that ultimately helped break down the barriers between Venter and Collins. The latter had implied all along that...
What's next? To get a fuller racial and gender mix, Venter will go through at least six more human genomes, probably including his own ("Why not, if that's the business I'm in?" he asks, admitting nothing). After the mouse, he'll probably go on to the chimp...
