title: Aphidicolin inhibits DNA replication in the micronucleus and blocks cytokinesis in Paramecium caudatum.
abstract: Aphidicolin, a selective inhibitor of DNA polymerase, totally blocks DNA replication in the micronucleus but not in the macronucleus of Paramecium caudatum. The ciliates no longer divide and after 4 days the DNA content of the macronucleus has increased by 64%. Concomitantly the cell volume has increased by 53%.
