So the advantage of using RNA in that cell is to basically make sure that we do not damage or hurt our DNA in any way. So we want to ensure that the DNA is not mutated because the DNA is essential for the survival of the cell as well as of the offspring. So during reproduction it's the DNA that is passed down and not the RNA. And so that means we have to make sure that the DNA is not damaged. And by using these RNA molecules we ensure that the DNA basically decreases the opportunity to damage itself. So we see that because our RNA is not passed down to the offspring our cells have no problem recycling or breaking down the damage or mutated RNA molecules.
