Credit: Gang Wang and William Pu/Boston Children's Hospital The series of images shows how inserting modified RNA into diseased cells causes the cells to produce functioning versions of the TAZ protein (from left, green), which correctly localize in the mitochondria (red). When the images are merged to demonstrate this localization, green overlaps with red, giving the third image a yellow color around its edges.
