The eukaryotic cell, the most significant increase in complexity in the history of life's evolution on Earth, emerged as a phase transition and unlocked the path toward other major transitions ...

Aug. 31, 2021 — In all eukaryotic organisms, genetic material is stored in the cell nucleus in the form of DNA. In order to be used, this DNA is first transcribed into messenger RNA in the cell ...

Ettema suspected that a cell from this family, later dubbed “Asgards,” might make a convincing candidate for that first hungry host that engulfed a bacterium that became a mitochondrion. If so, he ...

But once a cell achieves sufficient size and complexity, it eventually reaches a barrier, beyond which such prokaryotes can not pass. Or so the theory has it.

In two recent papers, an international team led by UC Santa Cruz scientists describe the first known nitrogen-fixing organelle within a eukaryotic cell. The organelle is the fourth example in history ...

Prokaryotic cells, which include all bacteria and archaea, are ancient, and relatively simple compared to eukaryotic cells, which are found in fungi, plants, and animals. Scientists have long sought ...
