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 ...

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 ...

Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the ...

One of the most diverse ecosystems on the planet is closer than you think - right inside your mouth. Your mouth is a thriving ecosystem of more than 500 different species of bacteria living in ...

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 ...

A Université de Montréal study has found a previously unknown mechanism in bacterial reproduction that could be attacked by ...

Researchers have revealed a surprising new role for a key protein in cell division. The discovery, reported in two back-to-back papers, challenges long-standing models and textbook accounts in biology ...

Chemists induced a cell-like behavior in molecular assemblies called vesicles. They used a sacrificial chemical fuel to make the vesicles divide into smaller versions of themselves. While this process ...

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 ...
