It makes backup copies. Self replication occurs in rather low level chemistry, as discussed in the video I linked. Doesn't require a genome or DNA or RNA.
Chemicals are not "alive" - neither are amino acids. Compare the failure of Urey/Miller to bootstrap life by simulating lightning strikes v. Wimmer's success to bootstrap the polio virus by starting with the message, e.g. RNA data off the internet.
I stand by my statement that every "thing" in space/time, including the lowly amoeba must pay the thermodynamic tab. And it does indeed pay that tab when it successfully communicates.
