摘要

In somatic mammalian cells, homologous recombination is a rare event. To study the effects of chro- mosomal breaks on frequency of homologous recombination, site-specific endonucleases were introduced into human cells by electroporation. Cell lines with a partial duplication within the HPRT (hypoxanthine phosphoribosyltransferase) gene were created through gene targeting. Homologous, intrachro- mosomal recombination between the repeated regions of the gene can reconstruct a functioning, wild-type gene.
