"Studying RNA enzymes. The graph in the foreground shows how the enzyme's catalytic activity is related to the rates at which the molecule folds and unfolds. These rates were measured by single-molecule fluorescence microscopy, where individual molecules light up as bright spots shown in the background. Also depicted, top right, is a ribbon-and-stick representation of the crystal structure of the folded RNA enzyme. "
