The nucleolar organizer
regions are chromosomal loops of DNA involved in ribosomal synthesis.
Functional sexual dimorphism of the nucleolar organizer
regions in the tuberomamillary nucleus.
Silver-staining analysis revealed the activity of nucleolar organizer
regions (NORs) on the short arms of both acrocentric chromosomes of autosomal pair number 6; the presumptive sex chromosomes did not show NOR activity (Fig.
region (NOR) distribution as a diagnostic marker in oral keratosis, dysplasia and squamous cell carcinoma.
regions (NORs) and myoepitheliomas: A comparison with DNA content and clinical course.
From the nuclear morphometry, and the morphometric analysis of the nucleolar organizer
areas, it is possible to optimize the prognosis for a better conduct orientation (Dantas et al.
Smears were also impregnated with silver in order to individualize nucleolar organizer
regions (NORs), in accordance with a technique previously described (18) with some modifications proposed by Aubele et al.
The diploid number, chromosome morphology, SDCS type, and behavior of chromosomes during meiosis were determined with conventional staining, and the distribution pattern of the active nucleolar organizer
regions (NORs) in the chromosomes was established using silver staining.
edule (Insua & Thiriot-Quievreux 1992) and standard karyotype, and the location of the nucleolar organizer
regions were described from Baltic and Mediterranean populations' of C.
This paper describes the diploid number, chromosome formula, and locations of nucleolar organizer
regions (NOR) in P.
Abbreviations: CI, centromeric index; FISH, fluorescence in situ hybridization; NOR, nucleolar organizer
46 [micro]m (Table 1) without a nucleolar organizer
region (NOR) is submetacentric; it has a terminal band and an interstitial band on the short arm; in addition to the centromeric band, a large interstitial band is located near the centromere on the long arm.
