Oh yes, propose completely unsimular things to avoid your problems. Which just creates more problems as now everything is dissimilar not similar.....What a load of nonsense.
Researchers in Italy have reconstructed one of the earliest evolutionary steps yet: generating long chains of RNA from individual subunits using nothing but warm water.
How Was RNA Polymerization Started?
A key step missing in the reconstruction of the origin of living systems is an abiotically plausible synthesis of RNA. To fill this gap, for the robust synthesis and the simultaneous presence of all the necessary nucleic acid precursors (which is possible in principle (22)), an abiotic procedure for their activation and a thermodynamically sound polymerization mechanism are needed.
Using this logic we have analyzed nucleotide oligomerization in the conceivably simplest solvent and environment: water at temperatures between 40 and 90 °C. Despite the limits set in principle by the standard-state Gibbs free energy change problem (3, 4), we observed that the process does actually take place in water and report the nonenzymatic formation of RNA chains in water from 3′,5′-cyclic nucleotides.
We describe three mechanisms for nonenzymatic RNA generation: RNA polymerization from monomers, RNA ligation, RNA extension by polymerization on pre-existing oligomers, and ligation. RNA ligation was recently reported in a model study performed on Poly(A) oligomers (10).
We observe that 3′,5′-cGMP polymerized into RNA chains at least 25 nucleotides long (Fig. 1), the predominant oligomer being the 8-mer. At the optimal 1 mm concentration, synthesis was fast, a Navg of 11.8 being reached within 1 min, followed by slow stepwise further growth. Canonical 3′,5′-phosphodiester bonds were formed, as determined by RNase sensitivity. 3′,5′-cAMP polymerized more slowly to oligomers that reached an Navg of 5.32 within 1 h. These oligomers expanded their size by inter-fragments ligation for a period of at least 200 h, yielding molecules >100 nucleotides long.
"Proto-RNA Bases" Assemble in Water, Hint at Origins of Life
Researchers at the Georgia Institute of Technology are exploring an alternate theory for the origin of RNA: they think the RNA bases may have evolved from a pair of molecules distinct from the bases we have today. This theory looks increasingly attractive, as the Georgia Tech group was able to achieve efficient, highly ordered self-assembly in water with small molecules that are similar to the bases of RNA. These “proto-RNA bases” spontaneously assemble into gene-length linear stacks, suggesting that the genes of life could have gotten started from these or similar molecules. The research is published online in the Journal of the American Chemical Society.
“The oligomers shown are the products of synthetic reactions lasting 1 h.”
After that 1 h? Dissolved.......
“which did not grow further.”
Funny how you left those parts out....
