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 ...

A new study, which appears in the current issue of the journal Nature Ecology & Evolution, challenges a popular scenario put forward to explain the arrival of the first eukaryotic organisms.

Two billion years later, complex life emerged in the form of large eukaryote cells with membrane-bound organelles, such as a nucleus and chloroplasts. The evolution of fungi, plants and animals ...

These discoveries give huge credence to the engulfment theory of how eukaryotic cells were born. To further investigate this ability in bacteria, the researchers hunted for other species with ...

That, to him, argues against a gradual evolution of the eukaryotic cell. In fact, some evidence suggests that key eukaryotic features were acquired all at once, rather than gradually.

Since translation mechanisms are conserved, researchers began to wonder if a similar phenomenon could be seen in the cells of eukaryotic organisms, such as plants, fungi, and animals.

Molecular biologists have discovered how ancient bacteria gradually evolved into mitochondria in eukaryotic cells 1. Those eukaryotic cells ultimately gave rise to all complex life forms, such as ...

In 2015, researchers examining deep-sea sediments near the underwater volcano Loki discovered gene fragments indicating a new and previously undiscovered form of microbes.

CVC also said that by March 1, 2012, the inventors had conceived of a CRISPR-Cas9 system in eukaryotic cells, and provided testimony, statements and emails from Doudna and Jinek to support this.

Since the 1960s, many experts have argued that the emergence of eukaryotes (cells containing a clearly defined nucleus) happened in response to the oxygenation of Earth's surface environment.

In the sleep-deprived fruit flies, mitochondria in sleep-regulating neurons began to leak electrons, which can lead to the production of reactive oxygen species, and more cellular damage. That ...
