Abstract
RNA enzymes have been developed that undergo self-sustained replication at a constant temperature in the absence of proteins. These RNA molecules amplify exponentially through a cross-replicative process, whereby two enzymes catalyze each other's synthesis by joining component oligonucleotides.
