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 ...

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 ...

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

Contrary to popular belief, bacteria have organelles too. Scientists are now studying them for insights into how complex cells evolved. Open a basic biology textbook published decades ago or one ...

Scientists have identified tubulin structures in primitive Asgard archea that may have been the precursor of our own cellular skeletons. In 2010, biologists made a shocking discovery. Living in the ...

THE CHEMICAL reactions on which life depends need a place to happen. That place is the cell. All the things which biology recognises as indisputably alive are either cells or conglomerations of cells ...
