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

eukaryotic cell is in flux, however, and an evolutionary sequence that appears simple when conceptualized on a phylogenetic tree diagram may be far more
complex and interesting in reality.
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.

complex are coupled oscillators, which together orchestrate the growth and division of
eukaryotic cells.»
All textbooks describe the cyclin - dependent kinase
complex as the one and only / exclusive regulator of the
eukaryotic cell cycle.

eukaryotic, meaning they have
complex cells, like plants and humans.
«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.
