Age-associated changes in the micronuclear cycle of Tetrahymena thermophila A III heterokaryons. A brief note.
The micronuclear cycle of Tetrahymena thermophila A III heterokaryons is shown to change with increasing clonal age. Autoradiographic and cytofluorimetric studies suggest that alteration may be due to (1) loss of late replicating sequences, or (2) (more likely) changes in the timing of micronuclear division and S with respect to cytokinesis.
