Abstract
The present invention provides novel methods for modifying the genome of an animal cell which typically comprise the steps of: constructing a DNA molecule in which desired sequence modifications are contained in a segment of DNA (a “targeting DNA”) that is substantially isogenic with a DNA in the cell genome (a “target DNA”); introducing the targeting DNA construct into the cell (e.g., by microinjection, electroporation, transfection, or calcium phosphate precipitation); and selecting cells in which the desired sequence modifications have been introduced into the genome via homologous recombination.
