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.

Eukaryotes—fungi, plants, us—are complex. Our large cells are characterized by their different compartments, many of which are neatly enclosed within a boundary of membrane. These compartments contain ...

A team of Chinese researchers has developed two new genome editing technologies, known collectively as Programmable Chromosome Engineering (PCE) systems. The study, published online in Cell on August ...

Plant and animal cells have a complex traffic system within them. This transport network links cellular compartments much like the traffic network that connects different districts in an urban ...

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 ...

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 ...

Cell polarity can be defined as a structurally and functionally asymmetric organization, in which the non-random positioning of each organelle, the function of which contributes to cell asymmetry, is ...
