Epigenetic controls in ciliates. Ciliates are protozoans with a unique characteristic: they possess two kinds of nucleus (this phenomenon is called nuclear dimorphism) a micronucleus used for inheritance, and a macronucleus, which controls the metabolism. On the division or reproduction of ciliates, the two nucleus are under several epigenetic controls.
