Dinosaur DNA Preserved
The researchers also isolated individual Hypacrosaurus cartilage cells and applied two DNA-stains, DAPI (4',6-diamidino-2-phenylindole) and PI (propidium iodide). These bind specifically to DNA fragments in extant material, and some of the isolated dinosaur cells showed internal, positive binding in the same pattern as seen in modern cells, suggesting some original dinosaur DNA is preserved (see below, right image).
