Delayed degradation of parental macronuclear DNA in programmed nuclear death of Paramecium caudatum

In the ciliated protozoan Paramecium caudatum, a parental macronucleus that is fragmented into some 40–50 pieces during conjugation does not degenerate immediately, but persists until the eighth cell cycle after conjugation. Here we demonstrate that the initiation of the parental macronuclear degene...
