To someone more knowledgeable than I: I've read a good deal about the origin of life. One oft-cited theory has to do with self-replicating strands of RNA. My question is, why RNA? I know it's simpler and more likely to come together in some sense than, say, a protein enzyme, but why is RNA favored over, say, something more like DNA? Is there something about ribose over deoxyribose, or uracil over thymine? Or can a ribozyme catalyst be made out of DNA as well?
Re: Why do self-sufficent 'ribozymes' use RNA and not DNA?
