Researchers originally theorized that DNA emerged before RNA. However, recent research on the origin of life suggests RNA developed before DNA. Explain why this theory was revised using the structure and function of each macromolecule as support.

RNA has great capability as a genetic molecule; it once had to carry on hereditary processes on its own. It now seems certain that RNA was the first molecule of heredity, so it evolved all the essential methods for storing and expressing genetic information before DNA came onto the scene.
