I did support it, but this may not be your area of expertise. This is why I asked someone in the know, to explain the consensus theory for why only single handedness within active bio-materials and how does the cell maintain this state of lowered entropy? I already know the answer but it is good to hear someone else say it. Enough distraction, I would like to talk about the DNA. I will get back to the boundary condition when it is time to link the two. Below is some data from an ACS publication concerning the enthalpies of formation of the nucleic acids. http://pubs.acs.org/doi/abs/10.1021/je800977n The enthalpy of formation tells us about the energy needed to form the various nucleic acids. The most interesting one is adenine. It has an enthalpy of formation of +225.7 kj/mole. This means we need to add energy to form adenine. This added energy is useful for the power of ATP because adenine is a hot molecule like a "mini TNT". The enthalpies of formation for uracil and thymine are, -301 and -338 kj/mole, respectively. These release a lot of energy when they form. The cytosine weighs in at, -69 kj/mole and guanine is calculated at +16 kj/,mole. These two are in the middle between the two extremes. If we went back to primordial times, all else being equal, the enthalpies of formation tells us something about the relative concentrations of available nuclei acids that would be around. Interestingly, the endothermic nature of adenine makes it harder to form and easier to disintegrate into entropy, thereby implying adenine was not in sizable proportions in the very early replicators, compared to the more exothermic ones which form easily and are at lower energy for more stability. What is also interesting are, the start codon is typically AUG (or ATG in DNA), or we need the mini-TNT to get the starting process going. Because adenine is endothermic in terms of formation, the expected small ratio of adenine might imply very few start markers in the first replicators. It was all about just plain ole replication practice.
