Reactive oxygen species (ROS) produced naturally during cellular metabolism often cause oxidative damage to cells. However, ...

The mechanical process of cell division exerts powerful, if microscopic, forces. How do the molecular machines that power it ...

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 ...

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 ...

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 ...

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 ...

If you took high school biology, you probably learned about cell division: a crucial process in all life forms officially called mitosis. For over one hundred years, students have learned that during ...

Every cell in the human body carries a record of its own history in the sequence of divisions that gave rise to it. This record contains information on how tissues are maintained, how cancers arise, ...

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 ...

It's long been assumed that when a parent cell divides into two daughter cells, the parent assumes a spherical shape, which then splits into two cells that have roughly the same, round size. But a new ...

An organism grows and repairs its body using a form of cell division known as mitosis. To divide, a cell must replicate the chromosomes, which carry the DNA (the instructions needed to build the body) ...
