Wow fascinating stuff, Kybosh. I had never even heard of Chirality.
I also found this upon searching a little deeper:
As nucleotide molecules come together to form the structure of DNA, they develop a twist that forms the double helix structure of DNA. DNA develops a twist in the chain because each component contains chirality or handedness. It is this handedness that gives DNA the spiral shaped helical structure. If one molecule in the DNA structure had the wrong chirality, DNA would not exist in the double helix form, and DNA would not function properly. The entire replication process would be derailed like a train on bad railroad tracks. In order for DNA evolution to work, billions of molecules within our body would have to be generated with the "R" configuration all at the same time, without error. If it is impossible for one nucleotide to be formed with chirality, how much less likely would it be for billions of nucleotides to come together exactly at the same time, and all of them be formed with the same chirality? If evolution cannot provide a mechanism that forms one product with chirality, how can it explain the formation of two products of opposite chirality?
Chirality is not just a major problem for evolution; it is a dilemma. According to evolution, natural processes must explain everything over long periods of time. However, the process that forms chirality cannot be explained by natural science in any amount of time. That is the dilemma, either natural processes cannot explain everything, or chirality doesn't exist.
If you're in doubt as to which is correct, you are a living example of the reality of chirality. Without chirality, proteins and enzymes could not do their job; DNA could not function at all. Without properly functioning proteins and DNA, there would be no life on this earth.
