The genetic characteristics of the human body consist of hereditary codes that form a series of molecules called nucleotides. The nucleotide consists of hypoxic hypoprotein, phosphorus root, a group of borins such as adenine and guanine, a group of pyrimidines such as thymine and cytosine, (DNA) contains a number of proteins, and it consists of two series of nucleotides that wrap around each other so that the adenine is a nucleotide Which is found on strings of nucleic acids present in one of the chains. The other chain contains thymine, and by hydrogen bonds the cytosine hydrogen base is connected to the guanine hydrogen base, which in turn leads to the formation of hypoxic ribosomal DNA. The DNA symbolizes abbreviated ribosomal DNA. DNA contains the oxygen-deficient ribosomal sugar and its nitrogenous base contains thymine. DNA consists of a double chain of DNA, and DNA stores information genetic person being is the main component of chromosomes, and when there is no change in the order of nitrogenous bases, consisting of DNA (DNA), it is a change in the genetic information stored in DNA, and thus changes in the cells when the person as this may lead to the occurrence of genetic diseases Tantq From grandparents and parents to children. The genetic information carried by ribosomal DNA is translated into proteins in the genes. The sequence of amino acids found in the proteins is determined by copying DNA molecules with negative charge and positively charged RNA molecules, which leads to the synthesis of chromosomes and converting them into amino acids. When new tissues and cells are present in the body and when cells divide, ribosome DNA replicates and replicates itself in these cells, and through the presence of repair enzymes in ribosome DNA, it can automatically repair itself. When ribosomal acid is exposed to strong and dangerous radiation such as radiation nuclear, X-rays, ultraviolet rays and it causes imbalances and distortions in nucleic acids, and these distortions can not those acids processed by itself, and therefore serious complications occur in a person's body tissue such as a cancer and genetic mutations that cause Deformities in the body of the person.
