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 ...

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 ...
