Genes

Genes are located on the “thread of life” DNA. The 25,000 genes in each human cell contain all the instructions needed to build and run the body. Most genes contain the instructions for making proteins. They are a sort of protein library. Some genes contain the genetic information for the production of ribonucleic acid (RNA).

These blueprints are encrypted. The encoding is made up of a combination of four chemical “letters” which are strung together like a long chain on the DNA. These four letters are A = Adenine, T = Thymine, C = Cytosine, and G = Guanine.
A combination of three of these letters, respectively, (e.g. AGT) forms a code word. This coding is deciphered by the protein factories of the cell (“ribosomes”). The ribosomes recognize that each three-letter word stands for one of a total of 20 building blocks of proteins, and according to this instruction, they assemble one building block after the other to form a complete protein.
