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, ...

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 ...

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

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 ...

By simulating the life cycle of a minimal bacterial cell—from DNA replication to protein translation to metabolism and cell ...

Biologists at the National University of Singapore (NUS) have uncovered how the protein NuSAP safeguards tiny structures inside cells called centrioles, revealing a mechanism linked to developmental ...

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, ...

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 ...

For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...

Ichthyosporeans Sphaeroforma arctica and Chromosphaera perkinsii undergoing mitosis, depicted as two halves of a cell, rendered in Haeckel-inspired tones and a naturalist style. Cell division is one ...

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 ...
