Centromeres are defined epigenetically and require the presence of the centromere-specific histone H3 variant centromere protein A (CENP-A). Although DNA sequences are not strictly required for ...

The centromere is the genetic locus required for chromosome segregation. It is the site of spindle attachment to the chromosomes and is crucial for the transfer of genetic information between cell and ...

About a third to two-thirds down the shaft of a chromosome is a constricted site called the centromere. When a chromosome replicates, the old and new pair (called chromatids) are held together at this ...

Since the 1800s, scientists have noted configuration of centromeres, a special chromosomal region that is vital for cell division, in the nucleus. Up until this point, however, the determining ...

Centromeres are curious structures. These specially organized chromosomal regions are best known for their unique and critical role in cell division, in which they are well understood to serve as the ...

Researchers have made a surprising new discovery in the structure of the centromere, a structure that is involved in ensuring that chromosomes are segregated properly when a cell divides. Mistakes in ...

An international research team has achieved a significant breakthrough in research into the reproduction of dogrose. The study, which has now been published in Nature, shows how differences in the ...

Just like you might use a belt to keep your clothes in place, the centromere holds a pair of chromatids together and attaches it to the mitotic spindle during cell division to ensure that each ...

The centromere of chromosomes plays a crucial role in cell division. Using the model plant Arabidopsis thaliana, an international team of researchers has investigated how two crucial proteins -- KNL2 ...

Some scientists call it the "final frontier" of our DNA -- even though it lies at the center of every X-shaped chromosome in nearly every one of our cells. It's called the centromere, and it plays a ...

A Japanese research team has mapped centromere positions across multiple Allium species, revealing striking diversity in size, stability, and mobility. Welsh onions showed stable centromeres of ...

Super-resolution microscopy image of a mitotic chromosome (white) with the centromeres of each sister chromatid depicted in orange. Each centromere consists of two distinct chromatin subdomains ...
