This implies that DNA and proteins evolved after RNA.

Explanation:

It is believed that RNA predated today's cells in evolutionary history. RNA existed as the genetic material of the primitive cells of the time that were mainly constituted of globules of fat oil suspended in water in the oceans and lakes. Even in cells today, RNA molecules themselves can act as catalysts such as in the case of peptidyl transferase reaction that takes place on the ribosome.
