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 ...

For a living cell to divide successfully, each daughter cell must inherit the correct genetic material. In eukaryotes, segregation of duplicated chromosomes is performed by the mitotic spindle, a ...

Osaka, Japan -- When a cell divides--a process known as mitosis--its chromosomes need to be separated and evenly distributed into the newly created daughter cells. Although this is known to be ...

Centromeres play virtually the same central role across the entire tree of life: They ensure the faithful segregation of ...

Chromosomes contains all genome information. During mitosis spindles attach a special structure of chromosome, which is called "centromere." In this study, we clarified how centromeres are formed on ...

Numerous errors in chromosome segregation during cell division can lead to the formation of micronuclei, even if there isn’t actual mis-segregation of the chromosomes. These events are not mutually ...

The exchange of DNA between chromosomes during the early formation of sperm and egg cells normally is limited to assure fertility. But when there are too many of these genetic exchanges, called ...

A research team led by Dr Karen Wing Yee YUEN, Associate Professor from the School of Biological Sciences at the University of Hong Kong (HKU), revealed the mechanism of artificial chromosome (AC) ...

Researchers have uncovered how successful chromosome segregation during sexual reproduction is achieved in plants. The discovery, by scientists led by the University of Leicester, could be beneficial ...
