Deciphering Protein Evolution
Barry Palevitz | Nov 25, 2001 | 5 min read
One of the enduring questions in biology is how eukaryotic cells arose from prokaryotic ancestors at least 2 billion years ago. Besides differences in genome organization, eukaryotic animals, plants, and fungi possess a much higher degree of cellular compartmentation in the form of membrane bound organelles than their distant bacterial and Archaean cousins. But how did such a plethora of cellular domains, each with a discrete role in metabolism, evolve? To the extent that science proves anythi
