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.
Famous quotes containing the word controls:
“If the Party could thrust its hand into the past and say of this or that event, it never happened—that, surely, was more terrifying than mere torture and death. ... “Who controls the past,” ran the Party slogan,”controls the future: who controls the present controls the past.””
—George Orwell (1903–1950)
