Researchers provide insight into an old mystery in cell biology, and offer up new clues to understanding cancer. Scientists have unraveled the mystery of how cells count the number of centrosomes, the ...

The centrosome is a small, non-membrane-bound organelle endowed with the remarkable capacity to nucleate and organize microtubules. It consists of a pair of centrioles — structures analogous to the ...

In animal cells, the centrosome nucleates microtubule polymerization, anchors those microtubules to create arrays that are capable of work, and duplicates exactly once per cell cycle. The centrosome ...

ROCHESTER, Minn. -- A Mayo Clinic discovery about a protein known as Dynamin-2 has thrown conventional wisdom for a loop. Finding the protein on the centrosome, a minute structure near a cell's ...

Cells are the building blocks of all living organisms. A large number of different cell types and forms exist that are adapted to the widely varying tasks they perform. These range from almost ...

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 ...
