New research by scientists at the University of Exeter has shown that cells demonstrate remarkable flexibility and versatility when it comes to how they divide - a finding with potential links to the underlying causes of many cancers.
The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests.
When an egg cell is being formed, the cellular machinery which separates chromosomes is extremely imprecise at fishing them out of the cell's interior.
Whitehead Institute scientists report that two proteins once thought to have only supporting roles, are the true "stars" of the kinetochore assembly process in human cells.
Scientists have discovered an amazingly simple way that cells stabilize their machinery for forcing apart chromosomes.
Whitehead Institute researchers have determined a key part of how cells regulate the chromosome/microtubule interface, which is central to proper chromosomal distribution during cell division.
If you can imagine identical twin sisters at rest, their breath drawing them subtly together and apart, who somehow latch onto ropes that pull them to opposite sides of the bedâ€”you can imagine what happens to a chromosome in the dividing cell.
â€œA biologist, a physicist, and a nanotechnologist walk into a ...â€ sounds like the start of a joke. Instead, it was the start of a collaboration that has helped to decipher a critical, but so far largely unstudied, phase of how cells divide.
- A transitional zone between two communities containing the characteristic species of each.
