摘要: Near the end of cell cycle, ciliates commit irreversibly to division. The point commitment occurs at time oral polykinetid assembly and micronuclear anaphase. is a checkpoint which requisites threshold mass/DNA ratio stomatogenesis. It also physiological transition point, involving cdk protein kinases similar those other eukaryotes. Both P34 kD P36 kinases, S. pombe cdc2 have been described activity as monomers. Subsequent division, dramatic cytoskeletal modifications occur for separation organelles, cortex morphogenesis cytokinesis. Numerous mutants affecting function associated with division process obtained in several species. Of these, only cc1 mutant Paramecium affects cycle progression prior material reviewed used speculate about mechanisms regulation pre-fission related processes ciliates.
