With a few exceptions, eukaryotic chromosomes have a single centromere that ensures their accurate segregation during mitosis. Chromosomes that lack centromeres segregate randomly during mitosis ...

The centromere of chromosomes plays a crucial role in cell division. Using the model plant Arabidopsis thaliana, an ...

Each arm of the chromosome is then divided into regions, and the numbers assigned to each region get larger as the distance from the centromere to the telomere increases. Regions are identified by ...

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 research team has clarified a mechanism of how retrotransposons, genetic elements that can 'jump around' chromosomes and are known drivers of evolution, preferentially insert in the centromere.

The findings were published in the journal Nature. The centromere is the thinnest part of the chromosome that divides it into a long and short arm, much like how the waist separates the upper and ...

A joint research group team led by Sayuri Tsukahara and Tetsuji Kakutani of the University of Tokyo has clarified a mechanism ...

Instead of storing genes, centromeres anchor proteins that move chromosomes around the cell as it splits. If a centromere fails to function, cells may divide with too few or too many chromosomes.

The centromere of chromosomes plays a crucial role in cell division. Using the model plant Arabidopsis thaliana, an international team of researchers led by the Leibniz Institute IPK has investigated ...

Replicated chromosomes remain attached to each other by their central region: the centromere. As long as they remain attached to each other the two identical copies of the chromosome are known as ...
