This achievement in 1953 is considered crucial in the history of biomedicine, because it began to persuade researchers in this field that DNA is the substance constituting the genetic material of all organisms on earth. It also gradually put DNA at the center of attention in science and society as the molecule directing the development and functioning of the living cell and our bodies.
