The first chromosome pair, besides centromeric coloration, presented a totally heterochromatic long arm. The nucleolus organizer regions (NORs) were studied by means of AgNOsub3/sub. NORs were located at the short arm of the second chromosome pair./p p class=apalavrachave/p 展开 ...
Nucleolus organizing regions (NORs) were detected on the short arms of the subtelocentric chromosome pair 13. Constitutive heterochromatin was identified at pericentromeric and terminal positions in almost all chromosomes. The W chromosome was almost entirely heterochromatic, except for a small terminal ...

The chloroplast of R. viridis (Rcp) and the nucleus (N) containing permanently condensed chromosomes and a large nucleolus (Nu) is also visible. B. Transverse TEM through the flagellar pocket (flp) showing paraxial rods (PR), the pocket (fep) and the microtubules of the feeding rod (arrow...
Furthermore, it has a unique nucleus with a peripheral nucleolus that attaches to the nuclear envelope opposite the basal body connection. Metabolomonas nov. gen. is extremely metabolic. It is characterized by a very high beating frequency of the anterior flagellum, fast gliding, rapid changes ...
Nucleolus organizer regions (NORs) were stained following silver nitrate impregnation [33]. The fluorescence in situ hybridization experiments were performed according to Pinkel et al. [34], with some adaptations described in Soares et al. [35] and Sassi et al. [36]. In summary, metaphase ...
Peroxisome, membrane-bound organelle occurring in the cytoplasm of eukaryotic cells. Peroxisomes play a key role in the oxidation of specific biomolecules. They also contribute to the biosynthesis of membrane lipids known as plasmalogens. In plant cells,
