RNA VERSUS DNA. “Early RNA-world is plausible because RNA can reproduce itself autocatalytically, which DNA cannot. Moreover, RNA controls the assemblage of amino acids into protein sequences. Some RNAs are as competent as proteins: it can splice itself, i.e. rearrange its own molecular shape anew – it rearranges and reorganizes genetic material.”
