Just like old times: Generating RNA molecules in water

Friday, November 20, 2009 - 13:21 in Biology & Nature

A key question in the origin of biological molecules like RNA and DNA is how they first came together billions of years ago from simple precursors. Now, in a study appearing in this week's Journal of Biological Chemistry, researchers in Italy have reconstructed one of the earliest evolutionary steps yet: generating long chains of RNA from individual subunits using nothing but warm water.
