Early-Earth Cells Modeled to Show How First Life Forms Might Have Packaged RNA ScienceDaily (Oct. 14, 2012) — Researchers at Penn State University have developed a chemical model that mimics a possible step in the formation of cellular life on Earth four-billion years ago. Using large “macromolecules” called polymers, the scientists created primitive cell-like structures that they infused with RNA — the genetic coding material that is thought to precede the appearance of DNA on Earth — and demonstrated how the molecules would react chemically under conditions that might have been present on the early Earth.
