Definition of Macronucleus. Meaning of Macronucleus. Synonyms of Macronucleus

- A macronucleus (formerly also meganucleus) is the larger type of nucleus in ciliates. Macronuclei are polyploid and undergo direct division without mitosis...
- a macronucleus that is primarily used to control metabolism, and a micronucleus which performs reproductive functions and generates the macronucleus. The...
- nuclear apparatus, consisting of a polyploid macronucleus, and one or more diploid micronuclei. The macronucleus controls non-reproductive cell functions...
- inheritance, and a macronucleus, which controls the metabolism. The micronucleus contains the entirety of the genome whereas the macronucleus only contains...
- Pseudomonilicaryon, which is distinguished from Dileptus by the shape of its macronucleus. The macronucleus of Pseudomonilicaryon is arranged like a string of beads, whereas...
- existing at a copy number of approximately 10,000 within the macronucleus. Because the macronucleus divides amitotically during binary fission, these minichromosomes...
- not express its genes. The macronucleus provides the small nuclear RNA for vegetative growth. Division of the macronucleus occurs in most ciliate species...
- nuclei (a large macronucleus and a single compact micronucleus). As in other ciliates, individuals cannot survive without the macronucleus and cannot reproduce...
- experiments of Aufderheide in 1986. These experiments demonstrated that the macronucleus, and not the cytoplasm, is responsible for clonal aging. Additional experiments...
- micronucleus and macronucleus. Unlike some other ciliates, C. uncinata contains millions of minichromosomes (somatic chromosomes) in its macronucleus while its...
