however , a bamhi subclone of the rad50-1 complementing plasmid failed to integrate at the rad50 locus , indicating that no homology exists between this fragment and the rad50 gene.a bamhi fragment from the rad54 plasmid was shown to be internal to the rad54 gene : its integration within a wild type copy of rad54 causes the cell to become rad ( - ) ;
