Organization of Genetic Material in the Macronucleus of Hypotrichous Ciliates

摘要: Hypotrichous ciliates (e.g., Euplotes, Oxytricha, Stylonychia), like most other ciliated protozoans, possess two morphologically and functionally distinct nuclei, macronuclei micronuclei. The are large, divide amitotically, function as somatic nuclei with nucleoli active ribonucleic acid (RNA) synthesis. Micronuclei small, by mitosis, have little or no RNA primary of a micronucleus is to give rise new macronucleus each time the cells undergo conjugation.
