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.

Every time a eukaryotic cell divides, it faces a monumental challenge: It must carefully duplicate and divide its genetic ...

An ambitious and revolutionary initiative aims to map every cell of all eukaryotic life on Earth. The result will be a ...

The 5′ cap is a unique feature of eukaryotic cellular and viral messenger RNA that is absent from the bacterial and archaeal domains of life. The cap is formed by three enzymatic reactions at the 5′ ...

Planctomycetes form a distinctive phylum of the Bacteria, having a unique combination of features such as peptidoglycan-lacking proteinaceous cell walls, and intracellular membranes that form separate ...

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 ...

The Golgi body (or Golgi complex, apparatus), and Endoplasmic reticulum (ER) are both organelles found in the majority of eukaryotic cells. They are very closely associated and show both similarities ...

The tubulin family of proteins are vital components of the eukaryotic cytoskeleton and are the main constituent of microtubules in living cells. The tubulin proteins α- and β polymerize into long ...

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 ...
