New findings shed light on how chromosomes manage the various pushing and pulling forces generated when cells divide. Specifically, researchers show that chromosomes resist being punctured by the ...

Mitosis is the mechanism by which a eukaryotic cell divides its nucleus and chromosomes to produce two genetically identical daughter cells. This biological process ensures the faithful transmission ...

During mitosis, sister chromatids are anchored to the mitotic spindle (microtubules originating from spindle poles) at their centromere by kinetochores. Microtubules can also be generated at ...

Cell biologists say they have, for the first time, directly observed and recorded in animal cells a pathway called branching microtubule nucleation, a mechanism in cell division that had been imaged ...

All life on earth depends upon the process of mitosis or cell division in which the chromosomal content of a cell is equally divided between two new cells. For mitosis to occur, the chromosomes in ...

Cell biologist Thomas Maresca and senior research fellow Vikash Verma at the University of Massachusetts Amherst say they have, for the first time, directly observed and recorded in animal cells a ...

It is well established that the mitotic spindle, the organelle responsible for chromosome segregation during mitosis, is built from microtubules, motor proteins, and associated structural and ...

A biological process taught to every pupil studying science at high school has just become a little more complicated thanks to a new discovery published today. Scientists from the University of Bath ...

This is a preview. Log in through your library . Abstract The structure of centric, intranuclear mitosis and of organelles associated with nuclei are described in developing zoosporangia of the ...
