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.
Nuclear power: a dangerous waste of timeThe unresolved legacy of nuclear power:radioactive materials â a continuing threat Introduction The nuclear power industry is attempting to exploit the climate crisis by aggressively promoting nuclear technology as a âlow-carbonâ means of generating electricity.hen a uranium atom is split, it produces not only energy but also highly dangerous radioactive waste. On average, uranium ore contains only 0.1% uranium. The overwhelming majority of the materials extracted during uranium ore mining is waste containing other hazardous radioactive and toxic substances.
