A Researcher preformed an experiment in which he exposed young corn plants to a harmless, radioactive form of carbon dioxide gas containing-14 instead of carbon-12. He then began feeding corn produced by the plants to a small group of goats. After several weeks, the researcher took blood and tissue samples from the goats. He was able to detect increased concentrations of carbon-14 in the goats' lipids, proteins, carbohydrates, and DNA.
