RNA can be a genetic molecule (like in some viruses), it can epigenetically control the expression of genes (like micro-RNA molecules), it can have enzymatic abilities (like ribozymes) and so on. The polymers could have assembled into units or structures that were capable of sustaining and replicating themselves.

Molecules of life met on clay. From these experiments, it seems reasonable to imagine that at least some of life's building blocks could have formed abiotically on early Earth. Do you believe that the diversity we see around us comes from a single origin of life event or multiple origin of life events? This early predator had an appearance much like a dinosaur. If we imagine that polymers were able to form on early Earth, this still leaves us with the question of how the polymers would have become self-replicating or self-perpetuating, meeting the most basic criteria for life. } But we can think in a more informed way about whether life might exist on other planets (and under what conditions) by considering how life may have arisen right here on our own planet.
