The phosphate is linked to the 5' carbon of the sugar in both RNA and DNA. The nitrogenous bases are adenine(A), guanine(G), cytosine(C), thymine(T), and uracil(U). Adenine and guanine are purines (contains a six membered ring of carbon and nitrogen fused to a five membered ring). Adenine and guanine are both found in DNA and RNA.
Uranium is a naturally occurring weakly radioactive element. High levels of uranium in water may increase the risk of cancer and kidney damage. Most of the uranium that is ingested by food or drink by the human body is excreted, but some amounts are absorbed into the bloodstream and kidneys.

Radioactivity The spontaneous decay of disintegration of an unstable atomic nucleus accompanied by the emission of radiation. Radioisotope A radioactive isotope. A common term for a radionuclide. Radionuclide A radioactive nuclide. An unstable isotope of an element that decays or disintegrates spontaneously, emitting radiation. Rate meter
