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

Centromeres are regions of DNA where the cell's machinery grabs each chromosome and pulls it into the two daughter cells. Centromeres are essential ...

A 'pocket' on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct order. Cell division is key for life. Every organism -- from the smallest yeast ...

Every second, millions of cells in your body divide in two. In the space of an hour, they duplicate their DNA and grow a web of protein fibers around it called a spindle. The spindle extends its many ...

When a cell divides, it performs a feat of microscopic choreography—duplicating its DNA and depositing it into two new cells.

Before a cell commits fully to the process of dividing itself into two new cells, it may ensure the appropriateness of its commitment by staying for many hours -- sometimes more than a day -- in a ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...

A "pocket" on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct order. Two studies by researchers at the University of Konstanz investigated ...
