RNA-lipid world (IMAGE) Technische Universität Dresden Caption A glimpse into an RNA-lipid world. The image shows a lipid membrane. The parts of the membrane that are more liquid are visible in magenta and the gel-like parts are visible as dark patches. The green RNA molecules concentrate at the membrane at the gel membrane domains. Such selective RNA-lipid interactions may have sparked the emergence of life in a prebiotic world. Nowadays, they can be employed in bioengineering applications. Scale bars represent 10 microns.
