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.
Radioactive decay, also known as nuclear decay or radioactivity, is the process by which a nucleus of an unstable atom loses energy by emitting radiation.A material that spontaneously emits such radiation â which includes alpha particles, beta particles, gamma rays and conversion electrons â is considered radioactive.he product is called the daughter nuclide. In some decays, the parent and the daughter nuclides are different chemical elements, and thus the decay process results in the creation of an atom of a different element. This is known as a nuclear transmutation.
