RNA world hypothesis
Information
The RNA world hypothesis proposes that self-replicating ribonucleic acid (RNA) molecules were precursors to current life, which is based on deoxyribonucleic acid (DNA), RNA and proteins. It is generally accepted that current life on Earth descends from an RNA world,although RNA-based life may not have been the first life to exist.
RNA stores genetic information like DNA, and catalyzes chemical reactions like an enzyme protein. It may, therefore, have played a major step in the evolution of cellular life
