Study finds that large embryo cells divide step by step using a mechanical ratchet system, challenging the textbook idea of a ...

Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying ...

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 ...

Researchers have revealed a surprising new role for a key protein in cell division. The discovery, reported in two back-to-back papers, challenges long-standing models and textbook accounts in biology ...

Trying to hit a target size before dividing seems like the best strategy for maintaining a precise cell size, but bacteria don't do that. Now we know why. When a single bacterial cell divides into two ...

Researchers at the Max Delbrück Center and the University of Oxford have found that a cellular housekeeping function called autophagy—by which cell components are broken down and recycled—plays a ...

The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...

About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it activates other proteins involved in this process. Plk1 is also ...

Scientists at the Ruđer Bošković Institute (RBI) in Zagreb, Croatia, have discovered that the protein CENP-E, long believed to act as a motor dragging chromosomes into place during cell division, in ...
