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.

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 ...

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, ...

Previously, chemists have managed to create artificial cell walls and developed synthetic DNA to produce self-replicating, synthetic bacterial cells. Now, for the first time, researchers have used ...

In 1905, Konstantin Mereschkowski postulated a symbiotic origin of plastids and animal cells 1, and in 1923, Ivan Wallin argued for a bacterial origin of the mitochondrion 2. Since then, dozens of ...

A planctomycete bacterium features structures embedded in its internal membranes which resemble eukaryotic nuclear pores, according to a study published February 1, 2017 in the open-access journal ...

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 ...
