    • Embodiments relate to methods of generating a genetically modified cell. The methods can include providing a primary cell containing an endogenous chromosomal target DNA sequence in which it is desired to have homologous recombination occur. The methods also can include providing a zinc finger endonuclease (ZFE) that includes an endonuclease domain that cuts DNA, and a zinc finger domain that includes a plurality of zinc fingers that bind to a specific nucleotide sequence within the endogenous chromosomal target DNA in the primary cell. Further, the methods can include contacting the endogenous chromosomal target DNA sequence with the zinc finger endonuclease in the primary cell such that the zinc finger endonuclease cuts both strands of a nucleotide sequence within the endogenous chromosomal target DNA sequence in the primary cell, thereby enhancing the frequency of homologous recombination in the endogenous chromosomal target DNA sequence. The methods also include providing a nucleic acid comprising a sequence homologous to at least a portion of said endogenous chromosomal target DNA such that homologous recombination occurs between the endogenous chromosomal target DNA sequence and the nucleic acid.
    • 实施例涉及产生遗传修饰的细胞的方法。 该方法可以包括提供包含在其中期望具有的同源重组好发源染色体靶DNA序列的一个主小区。 所述方法因此可包括提供一个锌指内切核酸酶(ZFE)确实包括在核酸内切酶结构域确实切割DNA,和一个锌指结构域也包括锌指的多元性没有绑定到特定核苷酸序列中的主要内源性染色体靶DNA内 细胞。 此外,该方法可包括使与所述主小区搜索的锌指内切核酸酶的内源染色体靶DNA序列,DASS死锌指内切核酸酶剪切的核苷酸序列的两条链的内源染色体靶DNA序列内的主小区,从而提高了 内源染色体靶DNA序列中的同源重组的频率。 因此,该方法包括提供核酸,其包含的序列同源的至少测试所述内源染色体靶DNA的一部分做了同源重组的染色体内源性靶DNA序列和核酸之间的发生。
