These rDNA regions are also called nucleolus organizer regions, as they give rise to the nucleolus.

B") differs from both M. mystacinus and M. brandtii in the pattern of active nucleolus organizer regions on the chromosomes.

"Chromomycin A3 Stains Nucleolus Organizer Regions of Fish Chromosomes".

The nucleolus organizer region (NOR) or nucleolar organizer is a chromosomal region around which the nucleolus forms.

During this period, she demonstrated the presence of the nucleolus organizer region on a region on maize chromosome 6, which is required for the assembly of the nucleolus.

Nucleolus organizer regions (NORs) have been identified by means of an argyrophilic technique (Ag-NOR) in routinely processed, formalin-fixed paraffin sections of breast lesions.

Nucleolus organizer regions (NORs) are head-to-tail arrays of genes encoding the precursor of the three largest ribosomal RNAs (18S, 5.8S and 25S in plants).

Although it also differs from other whiskered bats by morphological characters, Myotis alcathoe is most clearly distinct in its genetics, including DNA sequences and the location of the nucleolus organizer regions.

Although the banding patterns on the chromosomes of all slow lorises are similar, this species may be distinguished from the Bengal slow loris (N. bengalensis) by distinct differences in the number and location of nucleolus organizer regions.
