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:
“The confusion of emotions with behavior causes no end of unnecessary trouble to both adults and children. Behavior can be commanded; emotions can’t. An adult can put controls on a child’s behavior—at least part of the time—but how do you put controls on what a child feels? An adult can impose controls on his own behavior—if he’s grown up—but how does he order what he feels?”
—Leontine Young (20th century)
