A eukaryotic cell (left) has membrane-enclosed DNA, which forms a structure called the nucleus (located at center of the eukaryotic cell; note the purple DNA enclosed in the pink nucleus). A typical ...

Nuclear magnetic resonance measurement and state-of-the-art computational science reveal protein structures in higher eukaryotic cells. Researchers from Tokyo Metropolitan University have successfully ...

An exchange of genetic material that occurred when ancient giant viruses infected ancient eukaryotic cells could have caused the nucleus of the eukaryotic cell -- its defining feature -- to form. A ...

This article was originally featured on Knowable Magazine. More than 1.5 billion years ago, a momentous thing happened: Two small, primitive cells became one. Perhaps more than any event—barring the ...

Scientists can peer into cells to get a limited view of their activity using microscopes and other tools. However, cells and ...

Cilia are evolutionarily conserved, microtubule-based organelles that project from the surface of most eukaryotic cells and play a central role in sensing ...

These include stress granules and proteasome storage granules (PSGs). In the past, these membraneless organelles were only visible as “droplets” using a fluorescence microscope. Now, researchers from ...

Prokaryotic cells, which include all bacteria and archaea, are ancient, and relatively simple compared to eukaryotic cells, which are found in fungi, plants, and animals. Scientists have long sought ...

What is the last common ancestor of all plants and animals? Where did complex life come from and when? Scientists have been trying to answer these questions for many years. A new finding has changed ...

Molecular biology has something in common with kite-flying competitions. At the latter, all eyes are on the colorful, elaborate, wildly kinetic constructions darting through the sky. Nobody looks at ...
