    • The present invention provides a method of producing a cloned insert that is representative of the ends of a large segment of DNA from the genome of an organism. Specifically, the present invention provides a clone insert strategy that comprising the steps of: a) isolating a nucleic acid molecule, or portion thereof, wherein said nucleic acid molecule is at least 20 kb; b) ligating said nucleic acid molecule into a vector molecule; c) cutting said nucleic acid molecule with a restriction endonuclease, wherein said restriction endonuclease cuts said isolated nucleic acid molecule of step (a) in at least two sites but does not cut said vector DNA, d) ligating said cut nucleic acid molecule; e) transforming a host cell with said ligated nucleic acid molecule to propagate said molecule; f) determining the sequence of the ends of the nucleic acid insert and the sequence from the restriction endonculease site.
    • 本发明提供了一种克隆插入物的方法,该插入物代表来自生物体的基因组DNA的大片段的末端。 具体地说,本发明提供克隆插入策略,其包括以下步骤:a)分离其中所述核酸分子至少为20kb的核酸分子或其部分; b)将所述核酸分子连接到载体分子中; c)用限制性内切核酸酶切割所述核酸分子,其中所述限制性内切核酸酶在至少两个位点切割步骤(a)的所述分离的核酸分子,但不切割所述载体DNA,d)连接所述切割的核酸分子; e)用所述连接的核酸分子转化宿主细胞以繁殖所述分子; f)确定核酸插入物的末端序列和来自限制性内切酶位点的序列。
