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 new study challenges a popular scenario put forward to explain the arrival of the first eukaryotic organisms. In the beginning, there was boredom. Following the emergence of cellular life on earth, ...

Cells with nuclei are known as eukaryotic cells, the cells that make up animals, plants and yeast. The nucleus is the organelle that contains the majority of the cell's genetic material, where it is ...

Bacteria are different from you and me. Always the minimalists, they lack features that plant and animal cells usually can’t do without: a nucleus, special organelles, and an internal skeleton made of ...

A pandemic-era breakthrough has allowed scientists to literally expand our view of plankton. By using ultrastructure expansion microscopy, researchers visualized the inner workings of hundreds of ...

Researchers from UNIGE and EMBL reveal the internal structure of over hundreds of plankton species, paving the way for a global cellular atlas.

We’ve all seen the popular cartoon of evolution’s march from an ancient sea, beginning with a single floating cell that morphs into increasingly complicated creatures, on the way to the punch line of ...

The more researchers examine RNA, the more surprises they continue to uncover. What have we learned about RNA structure and function so far? Although RNA is a single-stranded molecule, researchers ...
