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

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 ...

Centromeres play virtually the same central role across the entire tree of life: They ensure the faithful segregation of chromosomes during cell division. Yet the striking diversity in centromere ...

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 ...

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 ...

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.

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 ...

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 ...

What am I looking at? This is a time-lapse video showing the dynamic nature of the ER in monkey kidney cells as they undergo cell division. The density of the ER network is represented by the ...
