Targeted Chromosomal Mutagenasis Using Zinc Finger Nucleases


The present invention provides for a method or methods of targeted genetic recombination or mutagenesis in a host cell or organism, and compositions useful for carrying out the method. The targeting method of the present invention exploits endogenous cellular mechanisms for homologous recombination and repair of double stranded breaks in genetic material. The present invention provides numerous improvements over previous mutagenesis methods, such advantages include that the method is generally applicable to a wide variety of organisms, the method is targeted so that the disadvantages associated with random insertion of DNA in-to host genetic material are eliminated, and certain embodiments require relatively little manipulation of the host genetic material for success. Additionally, it provides a method that produces organisms with specific gene modifications in a short period of time.
