Cell division during the early stage of embryo development is a trade-off between speed and accuracy; the cells need to ...

DNA does not float freely in the cell. Instead, it is wrapped around histone proteins to form structures called nucleosomes.

Activation of a specific part of the Dicer enzyme can change its shape in a way that affects its critical role in proper cell ...

Individual cells divide through a process called mitosis, during which the cell's copied DNA is separated between two resulting daughter cells. Despite recent advances in cell biology, the mechanism ...

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 ...

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 ...

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.

Cells in the human body accumulate cancer-promoting mutations throughout their lifespan, yet these mutations rarely drive tumour formation. Tumours in a given tissue usually originate from a specific ...

The Min protein system prevents abnormal cell division in bacteria, but is poorly understood. Researchers have uncovered how engineered e.coli bacteria control protein levels for maximum efficiency.
