| These proteins are expressed by all organisms ranging from prokaryotes to higher eukaryotes, including human cells. |
| In prokaryotes, mechanosensation is apparently limited to the detection of osmotic forces manifested as intracellular turgor pressure. |
| Hence it is certain that still more primitive life forms must have preceded the prokaryotes. |
| Why are extragenic mutations evidently more common in viruses than in prokaryotes or eukaryotes? |
| In a few organisms called prokaryotes, there is no defined nucleus and the DNA is found throughout the cell. |
| The bulk of the collection is the result of research on biostratigraphy, taxonomy, and biology of protists and prokaryotes at U.C. Berkeley. |
