Not exact matches

The consensus on the evolution of primitive life is that simple life forms (prokaryotes, organisms whose cells lack a distinct nucleus) inhabited the Earth about 3 - 4 billion years ago, eukaryotic cells (those with a nucleus which contains the genetic material) emerging 2 - 3 billion years ago.

Cells with nuclei, called eukaryotic cells (which make up virtually all multi-cellular organisms) are much larger and more complex that prokaryotic cells and likely resulted from the early combining of prokaryotic cCells with nuclei, called eukaryotic cells (which make up virtually all multi-cellular organisms) are much larger and more complex that prokaryotic cells and likely resulted from the early combining of prokaryotic ccells (which make up virtually all multi-cellular organisms) are much larger and more complex that prokaryotic cells and likely resulted from the early combining of prokaryotic ccells and likely resulted from the early combining of prokaryotic cellscells.

AS A species made up of eukaryotic cells complete with mitochondria, nuclei and other complex structures, it's easy for us Homo sapiens to look down on the far simpler prokaryotes, the cells of which lack such structures.

With a genome of this size, Pandoravirus salinus has just demonstrated that viruses can be more complex than some eukaryotic cells [2].

In the nucleus of eukaryotic cells, DNA is packaged with histone proteins into complexes known as chromatin, which are further compacted into chromosomes during cell division.

In fact, there's reason to believe that all of the properties of cell biology that made complex life possible in the next geologic era were put in place here: cytoskeletons that allow eukaryotic cells to change shape, and cell polarity that allows cells to send a molecular message to one side of the cell but not the other, and to interact with nearby cells.

In fact, as with eukaryotic organisms, division of Caulobacter cells generates two different daughter cells, which can be easily separated.

Martin Brasier at the University of Oxford says the stable period may also have been vital for the evolution of eukaryotic cells — cells with a nucleus of genetic material.

In previous studies, the same group along with others had demonstrated that microRNAs (miRNAs) produced by eukaryotic cells and viruses are present in human blood in highly stable, cell - free forms and these so called circulating miRNAs can serve as non-invasive biomarkers for the early diagnosis of various diseases, including viral diseases.

Unlike traditional eukaryotic cells — i.e. all cells with a nucleus — cryptophyte cells resemble a Russian doll in the form of an alga within an alga.

In this weeks» edition of Nature, researchers from Uppsala University in Sweden, along with collaborators from the USA, Japan, Denmark and New Zealand report the discovery of a new group of Archaea, the Asgard archaea, which reveal important details on how eukaryotic cells evolved their complexity.

«We found that Asgard archaea share many genes uniquely with eukaryotes, including several genes that are involved in the formation of structures that give eukaryotic cells their complex character.

However, even though the Lokiarchaea are relatively complex compared with other known archaea, they lack the large genome and energy - producing mitochondria of true eukaryotic cells.

Koonin describes the eukaryotic cell as a «palimpsest of fusions and gene exchanges,» referring to a manuscript that has been written over with new text.

We could fairly posit that the evolutionary origin of the eukaryotic cell was «the first time that what went around came around», a quid pro quo with among primitive organisms in deep time.
