Good morning Philip. All of the references I gave are online. You may view the abstracts at pubmed but you have to go to the journals for the full paper. Consider though, they are old publications and you may find newer research than what I posted (I would suggest biochemistry sources for this topic, molecular bio sources will just lead you to signal transduction work). As for your questions we first have to discuss inference. There is no way to tell the absolute source of an RNA particle unless it encodes for something (that is even a stretch). It is common to find RNA particles consisting of 4 to 10 bases on most surfaces (which are too small to encode anything). Now here is the inference part, if you place the parts needed for forming RNA in a vessel and supplied the right environment, RNA will form on its own. Now why we can infer that RNA occurs naturally is that all the parts of RNA form under the same types of conditions common in nature, all of which occur without influence by living organisms. Now keep in mind I am not suggesting that anything can be done with the RNA that forms, just that it does form. I can give you calculations of the energy states and why it is possible for RNA to form naturally, it will take a little time since I would be doing it by hand (I do not believe there is an easy source online for it). To make sure it makes sense to you, I need to understand how much you know about physical chemistry? You will need to understand a little about free energy and chemical equilibrium of biological molecules (basic chemical thermodynamics) and acid-base equilibria for any of the work to make sense. I can email you the finished diagram (with the equations), since I do not have upload, and you can upload it here if you wish. I have to admit I was looking forward to you asking for calculations; I have not worked on stuff like this since grad school. I am sorry about that formatting and will not use the reference tag on talk pages.--[[User:Able806|Able806]] 11:25, 16 January 2009 (EST)
