The meaning of chemical selection. Introduction: Most of the scientists favor RNA to be the very first macromolecule to be found in the protobionts. Comparative studies have shown DNA and proteins to be less versatile in comparison to RNA. During the origin of life on Earth, it is believed to be RNA dominant world. RNA world is believed to exist during the beginning of life on earth. It is a hypothetical period in early earth where both, the information required for maintaining life and the catalytic activities inside a cell were present in RNA itself.
