The kinetochore is a complex molecular machine that directs chromosome segregation during mitosis. It is one of the most elaborate subcellular protein structures in eukaryotes, comprising more than ...

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 ...

Researchers at Osaka University say they have clarified the structure of the centromeric region in chicken cells using cryogenic electron microscopy (cryo-EM). The team published its study in “The ...

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 ...

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 ...

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 ...

Since the 1800s, scientists have observed the configuration of centromeres -- a special chromosomal region that is vital during certain types of cell division -- in the nucleus. Up until this point, ...

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 ...

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