ribozymology

However, all the advances of ribozymology notwithstanding, the prospects of a bona fide ribozyme replicase remain dim as the ribozymes designed for that purposes are capable, at best, of the addition of ~10 nucleotides to a oligonucleotide primer, at a very slow rate and with fidelity at least an order magnitude below that required for the replication of relatively long RNA molecules [28,29].

Again, there is absolutely no teleology involved 2007
