Ribose and a diversity of structurally related sugar molecules are formed by a formose-type reaction in evolved pre-cometary ice analogues and detected by multidimensional gas chromatography. Ribose sugars make up the backbone of ribonucleic acid (RNA), which is what scientists think coded the genetic instructions for living things before the emergence of DNA. Credit: C. Meinert, CNRS
New research suggests that the sugar ribose – the “R” in RNA – is probably…
Scientists say the "R" in RNA may be abundant in space
