Small and weak heterochromatic bands were observed in the centromeric
region of the chromosomes in all the 3 species (Fig.
breaks, duplications, and deletions of the telomeric and centromeric
regions of chromosome 1) and numerical abnormalities, using probes for three repetitive sequence regions of chromosome 1: lcen (DIZ5, alpha, or A), lql2 (pUC1.
localization and adaptive evolution of an Arabidopsis histone H3 variant.
Data on relative length, arm ratio, centromeric
index and the chromosome classification for diploids are given in Table 2, and these for triploids are given in Table 3.
Human centromeres are believed to consist of large segments of highly repetitive DNA, called alpha satellite DNA, which is thought to play a significant role in centromeric
Dual-color FISH analysis was performed with a Spectrum Green-labeled chromosome 9 centromeric
probe and a Spectrum Orange-labeled, locus-specific CDKN2A (p16) probe (Vysis, Downers Grove, Illinois).
Located at highly conserved areas, primers CYP779f and Tena32F, by contrast, were able to unequivocally amplify fragments that cover the entire length of the CYP21 genes and its 2-sided flanking sequence at the centromeric
tail of the RCCX module, thus accurately identifying different types of chimeric CYP21A1P/CYP21A2 genes.
Nomenclature for the centromeric
position on the chromosome was according to Levan et al.
CCAN makes multiple contacts with centromeric
DNA to provide distinct pathways to the outer kinetochore.

4-kb SpectrumGreen (Abbott-Vysis, Inc) directly labeled DNA probe specific for the a satellite DNA at the centromeric
region of chromosome 17 (17p11.

The research presented today details how the Company incorporated two independent Y-chromosome probes; one centromeric
and one telomeric, to dramatically improve results.
The rationale for assessing amplification status as a ratio to the centromeric
region was to compensate for potential polysomy; however, detailed chromosomal analysis by comparative genomic hybridization and single-nucleotide polymorphism arrays have demonstrated that chromosome 17 polysomy is a rare event in breast cancer (7, 8).
