Abstract
As genome sequencing gets under way, investigators are grappling not just with new techniques but also with questions about what is acceptable accuracy and when data should be released. Four groups are embarking on projects that could make or break the human genome project. They are setting out to sequence the longest stretches of DNA ever tackled-several million bases each-and to do it faster and cheaper than anyone has before. If these groups can't pull it off, then prospects for knocking off the entire human genome, all 3 billion bases, in 15 years and for $3 billion will look increasingly unlikely. Harvard's Walter Gilbert, is first tackling the genome of Mycoplasma capricolum. At Stanford, David Botstein and Ron Davis are sequencing Saccharomyces cerevisiae. In a collaborative effort, Robert Waterson at Washington University and John Sulston at the Medical Research Council lab in Cambridge, England, have already started on the nematode Caenorhabditis elegans. And in the only longstanding project of the bunch, University of Wisconsin geneticist Fred Blattner is already several hundred kilobases into the Escherichia coli genome.
