Stretching the Rules: Monocentric Chromosomes with Multiple Centromere Domains [PDF]
, 2012 The centromere is a functional chromosome domain that is essential for faithful chromosome segregation during cell division and that can be reliably identified by the presence of the centromere-specific histone H3 variant CenH3.

Architecture of metaphase chromosomes and chromosome scaffolds. [PDF]
The Journal of cell biology, 1983 We have developed procedures for depositing intact mitotic chromosomes and isolated residual scaffolds on electron microscope grids at controlled and reproducible levels of compaction. The chromosomes were isolated using a recently developed aqueous method. Our study has addressed two different aspects of chromosome structure.

Chromosomal rearrangements in cattle and pigs revealed by chromosome microdissection and chromosome painting [PDF]
Genetics Selection Evolution, 2003 A pericentric inversion of chromosome 4 in a boar, as well as a case of (2q-;5p+) translocation mosaicism in a bull were analysed by chromosome painting using probes generated by conventional microdissection. For the porcine inversion, probes specific for p arms and q arms were produced and hybridised simultaneously on metaphases of a heterozygote ...

Cytogenetic studies in the genus Pentaschistis (Poaceae: Arundinoideae)
Bothalia: African Biodiversity & Conservation, 1998 Cytogenetic studies of 45 specimens, representing 16 taxa of the genus Pentaschistis (Nees) Spach confirmed two basic chromosome numbers (x = 7, 13) for the genus. Chromosome numbers for five species and one subspecies are described for the first time, i.

Chromosome instability in Alzheimer’s disease [PDF]
Archives of Biological Sciences, 2011 Alzheimer’s disease (AD), as the most common form of dementia, has for many years attracted the attention of researchers around the world, primarily because of the problems of reliable diagnostic methods that could help in the early detection of this ...

Non-random chromosome positioning in mammalian sperm nuclei, with migration of the sex chromosomes during late spermatogenesis. [PDF]
, 2005 Chromosomes are highly organized and compartmentalized in cell nuclei. The analysis of their position is a powerful way to monitor genome organization in different cell types and states.
