Abstract
The present invention is drawn to compositions and methods for introducing nucleotide sequences at preferred genomic target sites in a eukaryotic genome. The compositions comprise transfer cassettes which are flanked by nonhomologous recombination sites. The method involves transforming eukaryotic cells containing target sites utilizing non-integrating transformation methods. The method results in efficient integration of nucleotides into predetermined genetic locations and eliminates random DNA integration.
