Coacervate protocells (IMAGE) University of Chicago Caption Fluorescence microscopy image of three coexisting populations of stable coacervate protocells. The protocells contain long single-stranded RNAs, labeled with green, red, and blue fluorescent dyes. The absence of any intermixing of colors suggests that the exchange of RNA between the stable protocells is restricted.
