Chromosome Painting of Mouse Chromosomes [PDF]
Chromosome painting enables the visualization of chromosomes and has been used extensively in cytogenetics. Chromosome paint probes, which consist of a pooled composite of DNA-FISH probes, bind to nonrepetitive sequences for individual chromosomes [1, 2].

In RNA-mediated interference (RNAi), double-stranded RNAs (dsRNAs) target complementary mRNAs for degradation. New work demonstrates that essential chromosomal functions are mediated through RNAi protein components and short RNAs, which alter chromosome function at specific DNA loci via histone modification.

Holocentric chromosomes possess multiple kinetochores along their length rather than the single centromere typical of other chromosomes [1]. They have been described for the first time in cytogenetic experiments dating from 1935 and, since this first observation, the term holocentric chromosome has referred to chromosomes that: i.

The architecture of chicken chromosome territories changes during differentiation [PDF]
BACKGROUND: Between cell divisions the chromatin fiber of each chromosome is restricted to a subvolume of the interphase cell nucleus called chromosome territory.

Architecture of metaphase chromosomes and chromosome scaffolds. [PDF]
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.

Chromosome Oscillations in Mitosis [PDF]
Successful cell division requires a tight regulation of chromosome motion via the activity of molecular motors. Many of the key players at the origin of the forces generating the movement have been identified, but their spatial and temporal organization ...

Cytomolecular identification of individual wheat-wheat chromosome arm associations in wheat-rye hybrids [PDF]
Chromosome pairing in the meiotic metaphase I of wheatrye hybrids has been characterized by sequential genomic and fluorescent in situ hybridization allowing not only the discrimination of wheat and rye chromosomes, but also the identification of the

Dynamic epigenetic states of maize centromeres
The centromere is a specialized chromosomal region identified as the major constriction, upon which the kinetochore complex is formed, ensuring accurate chromosome orientation and segregation during cell division.

Y chromosome functions in mammalian spermatogenesis
The mammalian Y chromosome is critical for male sex determination and spermatogenesis. However, linking each Y gene to specific aspects of male reproduction has been challenging.
