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

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 ...

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 ...

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 ...

Animals and fungi predominantly use two different modes of cell division -- called open and closed mitosis, respectively. A new study has shown that different species of Ichthyosporea -- marine ...

The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...

Until now, cells dividing by mitosis were thought to grow round and then split into two identical, spherical daughter cells. New research has found that some cells are isomorphic, meaning they retain ...

Every day, our bodies perform around 330 billion cell divisions to keep us alive and functioning. These divisions rely on the cell cycle, which has been in place since the earliest bacteria. The ...

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 ...

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 ...
