Sugar on a stick : A DNA template can bind two complementary oligonucleotides, one derivatized with glyceraldehyde (blue) and the other with glycolaldehyde (red), resulting in a cross‐aldol reaction that forms pentose sugars. This reaction system serves as a model for the RNA‐catalyzed synthesis of ribose, which is relevant to a presumed RNA‐based metabolism during the early history of life on Earth.
