12/96--The new gene excision method uses a yeast gene identified as "FLP" and a segment of DNA that is 48 nucleotides long called "FRT." Researchers place two FRT segments on a chromosome so that they bracket the unwanted gene. Then they add the yeast gene, which produces an enzyme causing the chromosome to break at the FRT sites. The chromosome rejoins, without the unwanted gene.
