A eukaryote is any cell or organism that possesses a clearly defined nucleus. Eukaryotic cells form the foundation of complex, multicellular life, including apple trees, mushrooms, fish and humans.

In eukaryotes, DNA is tightly wound into a complex called chromatin. Thanks to the process of chromatin remodeling, this complex can be "opened" so that specific genes are expressed. Various molecules ...

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 ...

Scientists have identified tubulin structures in primitive Asgard archea that may have been the precursor of our own cellular ...

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 ...

Ribosomes translate genetic information encoded by messenger RNA into proteins. Many aspects of translation and its regulation are specific to eukaryotes, whose nbosomes are much larger and intricate ...

As a fundamental unit of life, the cell is central to all of biology. Better understanding how complex cells evolved and work promises new revelations in areas as diverse as cancer research and ...

Researchers have found striking parallels between how archaeal cells and more complex cells, including humans' and animals', package and store their genetic material. The breakthrough study provided ...

Coccolithophores are a type of single-celled microalgae that fix CO2 into organic matter and precipitate calcium carbonate, ...

A group of scientists from Japan--led by Prof Takashi Kamakura of Tokyo University of Science--has demonstrated, for the first time, the molecular and cellular basis of the "adverse" effects of the ...
