Abstract

The presence in some cells of Paeonia japonica of two satellites on each chromatid of the satellited chromosomes, indicates the chromatids are subdivided into at least two subunits and thus contain at least two DNA double helixes. Pulse labeling with3H thymidine reveals an asynchromous DNA replication pattern within the chromosomes. In some cases a region of one chromatid was labeled and the corresponding region in the sister chromatid was unlabeled. The most plausible explanation for this unichromatid labeling appears to be asynchronous DNA replication in a bineme model.
