or more commonly known as DNA. DNA exist as two long, fine strands of DNA spiraling into the famous figure of the double helix. The discovery of DNA is attributed to three scientist, Francis Crik, Maurice Wilkins, and James Dewey. All were given the Nobel Prize in physiology and medicine in 1962 (Lewin 1).
             Each strand of DNA is composed of millions of the essential chemical building blocks of life, chemical bases. "There are four bases Adenine (A), Thiamin (T), Guanine (G), and Cytosine (C). These bases can only be paired in certain order, (A) only with (T), (G) only with (C), and vice versa" (Barnes 180). The order of in which these bases occur determine the information available, much as specific letters combine to form words in a sentence.
             DNA resides in the nucleus of all of our cells, except the red blood cells. In each nucleus, there are forty-six molecules of coiled, double stranded DNA. Each one of these molecules is housed in a structure called a chromosome. Inside each chromosome are genes. Genes are the chemical message of heredity. "Genes constitute a blueprint of our possibilities and limitations, the legacy of generations of our ancestors, our genes carry the key to our similarities and uniqueness" (Genetic). Genes are made up of the chemical bases Adenine, Thiamin, Guanine, and Cytosine. These base in a certain order makes up codes, these codes determine if you are short, tall, fat, skinny, and etc.
             The sex cells are half of the forty-six chromosomes, twenty-three to be exact. In these cells, by random only certain genes are carried by the cells. When the sex cell from a man, sperm, and a sex cell fr
