In article <1992Oct30.195102.28879@cs.rochester.edu> dietz@cs.rochester.edu (Paul Dietz) writes: | |Sure, we've made RNAs in the laboratory -- using purified, chiral |tri(?)phosphorylated nucleotides, which (correct me if I'm wrong) |are extracted from biological sources. The *key* point is that we have made one that is *self-reproducing*, not merely that it was RNA. |Prebiotic Miller-Urey type |experiments have not, to my knowledge, ever produced nucleotides, nor |have they produced anything but racemic mixtures of mostly |biologically irrelevant molecules. I am fairly sure I heard about the production of nucleotides, and even short poly-nucleotides, in Meller-Urey type experiments. True, they were still racemic. -- sarima@teradata.com (formerly tdatirv!sarima) or Stanley.Friesen@ElSegundoCA.ncr.com
