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 ...

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 specialized chromosomal domains that direct kinetochore assembly during mitosis. CENP-A (centromere protein A), a histone H3-variant present exclusively in centromeric nucleosomes, is ...

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 ...

Probing the last genomic frontier of higher organisms, an international team of scientists has succeeded in sequencing a little understood - but critical - genetic domain in rice. MADISON - Probing ...

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 ...

České Budějovice/Gatersleben, 27.01.2020 Whenever the European dodder, Cuscuta europaea, is under scientific scrutiny, it usually is due to its lack of ...

We purified 15,000-fold from HeLa cell nuclear extract the centromere antigen that reacts specifically with the 17-bp sequence, designated previously as CENP-B box, in human centromeric α-satellite ...

Researchers from the Kops group in collaboration with researchers from the University of Edinburgh, made a surprising new discovery in the structure of the centromere, a structure that is involved in ...
