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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Despite the immense amount of genetic material present in each cell, around three billion base pairs in humans, this material needs to be accurately divided in two and allocated in equal quantities.

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 ...
