[Mitotic activity of different variants of heterophase homokaryons].

Double labelling with 3H- and 14C-thymidine was used to determine heterophase nuclei (G1-, S-, G2-) in homokaryons of the Chinese hamster cell culture. It was observed that the sequence of the mitosis beginning in homokaryons depends both on the number of nuclei in them and on the combinations of different phase nuclei.
