Not exact matches

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.

The eukaryotic tree of life from a global phylogenomic perspective.Cold Spring Harbor Perspectives in Biology.

The eukaryotic trunk of the tree of life sprouted branches leading to organisms ranging from yeasts to humans.

It is now recognized as one of the most important evolutionary innovations of life on our planet, and contributed to the origin of eukaryotic cells, which which humans are made of.

One of the main findings that we have obtained thus far, is that the eukaryotic lineage seem to branch from within the archaeal Domain of life, affiliating with the so - called «TACK» superphylum (comprising Thaum -, Aig -, Cren - and Korarchaeota).

We find homologs in genomes across the eukaryotic tree of life, map known and de novo protein functionalities, and examine co-evolution between proteins and protein motifs.

All eukaryotic cells — the kind that make up all multicellular life — owe their existence to the two creatures that underwent this fateful merger.
