  16. The effectiveness of the nuclear localization signal selected was clearly tested in initial experiments. based on this, the co - transfection systems used in the study was established. we first observed the multinucleate cells and chromatin bridges in cultured hela cells when the cells are marked with gfp and hochest33342, after co - transfection with the gfp expression plasmids and rnai plasmids rhe or rhc
