Quotes About Eukaryotes

Eukaryotes evolve morphological responses to environmental challenges—in other words, they develop new body shapes and body parts—which leads to a variety and freshness that is absent in the prokaryotes.

Eukaryotes topped that trick with yet another innovation—an elaborately orchestrated breakthrough in cell-division called meiosis.

One may code for wrinkles, while the other holds the blueprint for smooth. As long as they stay together, only the stronger of each pair rules. Eukaryotes took advantage of this disagreement between twins. Prokaryotes had xeroxed chromosomes in their entirety. But eukaryotes unzipped their chromosomal ribbons lengthwise, ever-so gently separating each genetic pair. This yielded two skinny juliennes,‡ each with slightly different properties.

Eukaryotes thus launched a great leap forward in data mix-and-matching, one which roils and churns within us to this day. We latter-age eukaryotes call the resulting DNA cut-and-shuffle sexuality.

Dorian Purcell, focused intensely on archaea, the third domain of animal life. The first domain is eukaryotes, which includes human beings and all other higher organisms. The second domain is bacteria. Microscopic archaea, which lack a nucleus, were long thought to be a kind of bacteria. But they have unique properties, not least of which is the ability to effectuate horizontal gene transfer.

The amount of DNA not coding for RNA, sometimes called junk DNA (a dangerous term for something one does not understand), is also much greater in eukaryotes.
