So what happens is the sequencers actually, what we do, and the sequencers, are really quite separate. So the sequencers do their machines, they push data to another set of computers and that eventually gets pushed into the public databases. And then from the public database we take that information, including all the other information from other centers like Whitehead or St. Louis, and then that gets processed. That gets held on our computers, and gets processed by the farm here. And then at the end of that processing we then display all the results of that processing on the Web.
For the first draft of the genome sequence, both teams were working to identify the number of human genes. Here, Ewan Birney, a "numbers man" from the public genome project, explains how genes can be recognized and the data from the genome project used.
