Infinity Learn · Accepted Answer

RNA acts as genetic material in some viruses and all viroids. It behaves as catalyst for the formation of peptide bonds during translation (23S$$ rRNA, $$28S$$ $$rRNA). Metabolism, translation and splicing have evolved around RNA. DNA is formed from RNA upon some chemical modifications in Ribose sugar and the nitrogen base Uracil.
