Microtubules, the dynamic filaments that form the cell's internal scaffolding, have long been viewed as mere passive structural supports. But a new study reveals they play a far more active signaling ...

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) ...

If cells in cell cultures grow while being treated with division-suppressing agents, their growth becomes excessive and they permanently lose their ability to divide. However, if the cells are treated ...

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 ...

A living cell is a bustling metropolis, with countless molecules and proteins navigating crowded spaces in every direction. Cell division is a grand event which completely transforms the landscape.

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, ...

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 ...

A metabolic enzyme also binds and unwinds RNA to promote translation of cell cycle genes. This dual role links energy status ...

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 ...
