An illustration depicting the formation of RNA before DNA. The images show:

1. Simple organic molecules combine to form RNA neucleotides.
2. RNA is able to replicate itself, synthesize proteins, and function in information storage.
3. From this, several steps, could have followed. These are:
   • Proteins build cell structures and catalyze chemical reaction.
   • RNA helps in protein synthesis
   • DNA functions in information storage and retrieval.
