The Ciliate Euplotes as Teaching Materials for Cell Cycle

Abstract

In ciliate Euplotes, the special structure called replication band (RB) appears on the S-phase nucleus. The RB can be easily observed in the nucleistained with aceticcarmine. By using the ciliate with this unique phenomenon, the cell cycle was especially examined on the relationships between the cell growth and the cell cycle, and also between the conjugation and the cell cycle. The ciliate is discussed as teaching materials for cell cycle.
