The last step of the cell cycle is the brief but spectacularly dynamic and complicated mitosis phase, which leads to the duplication of one mother cell into two daughter cells.
Team finds that Orc1, part of machinery that initiates DNA replication, prevents excess centrosome duplication.
Dartmouth Medical School researchers have found two proteins that work in concert to ensure proper chromosome segregation during cell division. Their study is in the January 2009 issue of the journal Nature Cell Biology.
A group of Dartmouth researchers has found a new function for one of the proteins involved with chromosome segregation during cell division.

Scientists have long known that the social insects in the order Hymenoptera--which includes ants, bees, and wasps--have an unusual mechanism for sex determination.
One of the key controllers of neural development seems to depend on a simple cellular decision--whether to divide perpendicularly or in parallel to the embryonic structure called the neuroepithelium. Nevertheless, such orientation is critical, and understanding its machinery could help neuroscientists learn to control the division of adult neural stem cells to regenerate neural tissues.
Arbacia punctulata is a species of Arbacia genus of purple-spined sea urchins. Its natural habitat is in the Western Atlantic Ocean. It can be found in shallow water from Massachusetts to Cuba and the Yucatan Peninsula, from Texas to Florida in the Gulf of Mexico, the coast from Panama to French Guiana and in the Lesser Antilles, normally on sandy, rocky, or shelly bottoms. It is omnivorous, consuming a wide variety of preys. It’s been shown that it is galactolipids, rather than...
