CBM scientists give answers in a publication published in the Journal Nature Communications. Why is Furanose the only sugar found in the composition of DNA and RNA while this form of sugar is not the most stable, so not the most abundant, in temperature conditions and pressure we are currently experiencing? These are the hydrothermal sources, omnipresent on the surface of the primitive land, and their complex thermal influence, which could be at the origin of this selectivity. This study conducted by scientists from the Molecular Biophysics Center, which is the subject of an article in the Nature Communications journal, should make it possible to better understand why and how molecules come together to give life in a primitive geological context.
