DNA Double Helix stores genetic information.     DNA Polymerase replicates DNA.

   RNA Polymerase synthesizes RNA from DNA.   Ribosomes use RNA to build proteins

These four biological molecules are essential to all life on Earth.

They originated more than 3 Billion years ago during the Proterozoic Era, in a common ancestor of Bacteria, Archaea, and Eukaryota.  Together these molecules form the fundamental pattern of the fractal of life; they are specialized machines that replicate each other and produce an endless variety of new forms.  They have evolved over trillions of generations into extraordinarily complex arrangements that consume energy, organize, and reproduce.
