The pattern of acrocentric chromosomes was studied in 190 normal and 190 trisomic cells from a patient with trisomy 21 mosaicism. No significant differences were observed in the total numbers of associations, the numbers of mitoses with one, two, or three associations, or the numbers of associations
The frequency of involvement in satellite association and the frequency of selective staining of the secondary constrictions with silver solutions have been studied in five phenotypically normal individuals, all carriers of morphological variants of the nucleolus organizing region (NOR). The results
A silver staining technique developed by Goodpasture and Bloom (1975) stains a specific protein associated with the activity of ribosomal cistrons during the preceding interphase. By counting the number of chromosomes with darkly stained nucleolus organizer regions (NORs), the number of active NORs
