DNA is the basic genetic material that is passed from generation to generation on the chromosomes. DNA is found in the human cell. That too in cell nuclei, the powerful central point in the cell. It is like atom nuclei. This cell nuclei controls protein manufacturing in the cells.

From these nuclei an acid is produced. It is called nucleic acid. This gives an image into the way in which life may begin on earth.

The dissolved salts in the ancient ocean combined with methane and carbon dioxide (i.e., in the atmosphere nature). The energy supplied by light and the ultraviolet radiations helps the image as well as the varied images of the lives in the world.

The salt in the ocean is an organic component. It has the amino acid in it. These compounds collected on metals rich seabed rocks. It serves and acts as catalysts helping in building organic molecules into nucleotides and eventually perhaps into nucleic acid and is termed a DNA cell.
