Digestion of polyoma viral DNA with a restriction enzyme from Haemophilus aegyptius generates at least 22 unique fragments. The fragments have been characterized with respect to size and physical order on the polyoma genome, and the 5' to 3' orientation of the (+) and (-) strands has been determined. A method for specific radiolabeling of adjacent fragments was employed to establish the fragment order. This technique may be useful for ordering the fragments produced by digestion of complex DNAs.
用来自埃及嗜血杆菌的一种限制酶消化多瘤病毒DNA可产生至少22个独特的片段。这些片段已根据其大小、在多瘤病毒基因组上的物理顺序进行了表征,并且已经确定了(+)链和(-)链从5'到3'的方向。采用一种对相邻片段进行特异性放射性标记的方法来确定片段顺序。该技术可能有助于对复杂DNA消化产生的片段进行排序。
