The substance of the replicator model is that all that matters in life is information, and all that matters in evolution is the replication of information with occasional mistakes. But we have seen that at the heart of life there are two fundamental entities, not one. Information and meaning are two independent entities, copying and coding are two independent processes, and the codemaker between genes and proteins must be a third party because otherwise there would be no... 

The mutagenic ribonucleotide rPTP (87) has been used in an in vitro retroviral replication model. After four rounds of replication the mutation frequency was raised to 3.8 x 10 per nucleotide, with C U and U C mutations observed. It was suggested that such an analogue could induce mutations in a retroviral target beyond its error threshold. The tricyclic cytosine analogues phenoxazine and 9-(2-aminoethoxy)-phenoxazine (g-clamp, see (141)) have been incorporated into ODNs to study their effect with exonuclease. It was found that a single substitution at the 3 -terminus afforded complete protection of the ODN with snake venom phosphodiesterase. ...

Commoner [113] has criticized the replication models proposed by Watson and Crick. On the basis of observations on physical models. Commoner claims that in the case of a linear code as complex as the one storing all the information locked in a single DNA molecule, the individual signals emitted by each complementary base of the primer strand to attract the new base would be lost in the background noise emitted by the molecule as a whole. Furthermore, according to Commoner, the biosynthesis of DNA as pro-...
