| | Prokaryote - Wikipedia, the free encyclopedia |
 | | Many prokaryotes live in or on the bodies of other organisms, including humans. | | | Archaea in particular seem to thrive in harsh conditions, such as high temperatures or salinity. | | | Organisms such as these are referred to as extremophiles. |

| | Prokaryotes |
| | The complex metabolic pathways necessary to maintaing life, to grow, and to reproduce, show an astonishing amount of variety among different kinds of prokaryotes, a variety that we are just beginning to understand. | | | Same for a cup of seawater, or the bacteria in a person’s mouth, or on a person’s skin. | | | Although prokaeryotes are thought of as single-celled organisms, some live in transient aggregations, and some form true colonies. |

| | Prokaryote Ancestors of Actin |
| | Taken together it seems that actin was a prokaryotic invention like most things in life! | | | The ever increasing number of complete genomes is now beginning to answer it however, and it turns out that just as tubulin has an identifiable prokaryote ancestor (FtsZ, which is involved in bacterial cytokinesis), so does actin. | | | Actin is a notoriously conserved protein there being trivial differences between the actin sequence from amoeba to man. It was as it actin had been "invented" once and immediately spread throughout organisms like life jackets on the Titanic when the iceberg struck. |

| | Prokaryotes are unicellular organisms that do not develop or differentiate into multicellular forms. | | | Prokaryotes also lack any of the intracellular organelles and structures that are characteristic of eukaryotic cells. | | | Bacteria are the best known and most studied form of prokaryotic organisms, although the recent discovery of a second group of prokaryotes, called archaea, has provided evidence of a third cellular domain of life and new insights into the origin of life itself. |

| | Prokaryotes |
| | Prokaryotes are the single-celled organisms, such as bacteria, and are roughly one micrometer in diameter. | | | Additionally, at the time of Symbiosis, prokaryotes were anaerobic, that is, they did not respirate oxygen as a fundamental necessity to live. | | | One differentiating characteristic is that prokaryotes are asexual, meaning their offspring nearly always bear the exact characterisitcs of the parent cell. |

| | Prokaryote - EvoWiki |
| | Prokaryotes are single celled micro-organisms characterized by the lack of a membrane-bound nucleus and membrane-bound organelles. | | | The word "prokaryote" is from Greek and means "before the nucleus". | | | This definition can be misleading if approached from the evolutionary ladder view: eukaryotes (organisms with nuclei) are not evolved from prokaryotes, the two share a common ancestor, whose cells almost certainly looked nothing like modern prokaryotic cells. |

| | Inherent Size and Complexity Constraints in Prokaryote Gene Regulatory Networks by M. J. Gagen |
| | This model explains the observed quadratic growth in regulator number with gene number and predicts an upper prokaryote size limit closely approximating the observed value. | | | However, if for any reason the network cannot tolerate such gross structural changes then accelerating networks are constrained to have sizes below some critical value. | | | Our generalized models then predict an upper limit to the size and complexity of prokaryote genomes which is very close to that observed in the evolutionary record. |
