GENOMICS:
Fruit Fly Genome Yields Data and a Validation
Elizabeth Pennisi
WASHINGTON, D.C.--Using an approach dismissed as unworkable a mere 2 years ago, a team of publicly and privately funded scientists announced last week that they had decoded more than 97% of the genome of the fruit fly Drosophila melanogaster. As with all genome projects, parts are missing: The team sequenced only gene-containing regions, and about 1600 gaps remain. Even so, Drosophila, which has been long studied by geneticists, is the largest creature ever to be sequenced, genomewise, and only the second multicellular organism.
