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.

Of all eukaryotic organelles, the nucleus is perhaps the most critical. In fact, the mere presence of a nucleus is considered one of the defining features of a eukaryotic cell. This structure is ...

Until recently, the origins of these microtubules were unclear. In a newly published Cell study, the ETH team identified similar structures in Asgard archaea.

In comparison, eukaryotic cells contain two types of rRNA genes that give rise to four rRNA species: the 28S, 5.8S, 5S, and 18S rRNAs.

Origin-recognition complex (ORC) plays an unexpectedly broad role in the regulation of human cell gene expression, according ...

Bacteria are amongst the simplest of organisms - they are made of single cells. Their cell structure is simpler than the cells of animals, plants and fungi. Size Most are 5 μm - 100 μm. Most are ...

Eukaryotes and prokaryotes Bacteria are amongst the simplest of organisms – they are made of single cells. Their cell structure is simpler than the cells of animals, plants and fungi.

When I first learned about the eukaryotic cell structure, I marveled at the sophisticated simplicity of how organelles synergistically work with one another to ensure smooth cellular processes. On the ...

Researchers discovered that epithelial cells reshape the endoplasmic reticulum (ER) to sense tissue curvature and coordinate ...

Cell biology covers all aspects of the structure and function of eukaryotic cells. Students in this field study the integration at the cellular level of biochemical, molecular, genetic ...
