  Abstract: Prominent current ideas on how life emerged on Earth include an RNA world hypothesis in which RNA performed informational as well as catalytic functions in the absence of both DNA and protein. Demonstration of a self-replicative system based on ribonucleic acid polymers as both information carriers and catalysts would lend support to such a scenario. A pivotal component of this system would be an RNA dependent RNA polymerase ribozyme capable of replicating its own RNA gene. Recent work from the Holliger group at the Laboratory for Molecular Biology in Cambridge has provided synthetic ribozymes1 that just might foreshadow the future engineering of such self-replicative systems.
