Single celled organisms

The Origins of Life From Single celled organisms to modern humans, two
chemical compounds have created life.

Approximately 3.5 billion years ago single celled organisms developed on earth. These first cells were created by two molecules, nucleic acids, and amino acids. Even today cellular life still relies on nucleic acids (DNA & RNA), and amino acids.


DNA has recorded earthly organisms evolution. And we now understand evolution is caused by mutations in genes, and survival is the driving force. Genes are sections of the DNA sequence that carry instructions to build proteins. Proteins are macromolecules composed of individual amino acids bonded together in polypeptide chains that are folded into three dimensional shapes.


Life on earth would not be possible without protein synthesis. The relationship between nucleic acids, and amino acids created the first cells on earth and are continuing to create, grow, and evolve new life today. Plants, animals, humans, bacteria, and all other cellular life on earth require these two molecules and all of their chemical processes.
