So I read this post in the Scientific American entitled " How Structure Arose in the Primordial Soup" by Emily Singer and Quanta Magazine, which discusses how DNA arose through the beginnings of life, or lack of knowledge about the event itself. The article discusses the views of scientist Greg Fournier is attempting to use genomic data from present species to infer the genetic code of those ancient genes present in the primordial soup. He believes the last amino acid to be added was tryptophan. Other scientists believe that the genetic code began from a limited alphabet of amino acids, with that developing into the complexity of the diverse life forms of today.

Essentially the idea of primordial soup establishes that radiation coverts gases such as methane and ammonia into the first organic compounds, monomers, and eventually into polymers, etc. This theory has been overturned, and now the idea is that organisms today use the same proton gradient to drive ATP as the less evolved did millions of years ago. So how did it happen?

The Miller-Urey experiment explored the possibility of the primordial soup theory through experimentation with abiogenesis, which produced some of the amino acids necessary for life using
"lightning" . However, could this experiment be expanded or manipulated so that the amino acids could turn into protein so that primordial soup conditions are met? Or is the new theory correct?

In experimentation to test the theory, scientists used a simulation of a meteorite impact to test for ATP related substances, because of the necessity of the substance in lifeforms, and it is thought there was an absence millions of years ago. The experiment showed that an ATP like substance was produced, which could have possibly been used to make more extensive lifeforms.

However, all of the research done is only yields a possibly, and I hope to see research done which has the missing link from amino acid to DNA, because it seems to me that these experiments are inconclusive and do not actually show how structure arose from primordial soup or from chemiosmosis.Why is that? Once again I pose, is it possible? Below are the resources that I used.
