micronucleus उदाहरण वाक्य

As a ciliate, " C . uncinata " has cilia covering its body and a dual nuclear structure, the micronucleus and macronucleus.
Ciliates contain two nucleus types : a macronucleus that is primarily used to control metabolism, and a micronucleus which performs reproductive functions and generates the macronucleus.

In " Tetrahymena ", the micronucleus has 10 chromosomes ( 5 per haploid genome ), while the macronucleus has over 20, 000 chromosomes.
Ciliates are also capable of sexual reproduction, and utilize two nuclei unique to ciliates : a macronucleus for normal metabolic control and a separate micronucleus that undergoes meiosis.

Many micronucleus assays have been developed to test for the presence of these structures and determine their frequency in cells exposed to certain chemicals or subjected to stressful conditions.
The cytokinesis-block micronucleus ( CBMN ) assay was first developed to score micronuclei in cells that completed nuclear division by blocking them at the binucleate stage before cytokinesis.
There is apparently little, if any, DNA damage in the new macronucleus, suggesting that rejuvenation is associated with the repair of these damages in the micronucleus during meiosis.
This species can be distinguished from its congeners by its large body size and the shape of the macronucleus; this species'micronucleus is located situated in a small macronuclear concavity.
Unlike most other eukaryotes, ciliates have two different sorts of nuclei : a tiny, diploid micronucleus ( reproduction ), and a large, polyploid macronucleus ( general cell regulation ).
