234 | Tobias Warnecke on Cellular Structure and Evolution

Eukaryotic cells manage to pull off a number of remarkable feats. One is packing quite a long DNA molecule, with potentially billions of base pairs, into a tiny central nucleus. A key role is played by histones, proteins that provide scaffolding for DNA to wrap around. Histones also appear in archaea (one of the other domains of life), but until recently there wasn't evidence for them in bacteria (the final of the three domains). Todays guest, Tobias Warnecke, is an author on a recent paper that claims to provide such evidence. We discuss this new result, as well as background questions of how cells evolved and what their current structure can teach us about their histories.
