Human cells have two copies of each chromosome, and this balance is essential for genes to be expressed in the appropriate ...

Researchers at the University of Illinois Urbana-Champaign have built a computer simulation that tracks the entire life cycle ...

A simulated cell in the early stages of division. Left half shows membrane (green cubes), and ribosomes (yellow/purple) interwoven through in the cell’s chromosome (red). Right side shows all the ...

A metabolic enzyme studied for over seven decades has a hidden second function—it can unwind RNA and promote cell cycle progression, an additional function beyond its role in energy production, ...

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 remarkably small bacterium containing fewer than 500 genes serves as the basis for one of the most detailed digital life ...

Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and ...

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 ...

Bacterial cell division is a fundamental biological process that ensures the propagation of life through a precisely orchestrated set of events. Central to this process is the formation of the Z ring, ...

Before cells can divide, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Until now, scientists had believed that ...
