Genes and epigenesis

The sense of life has been searched in the genes. It is supposed that, if atom Kingdom could be reached, the point where the not-life transforms itself into life could be found too looking through a microscope. That is not the truth. Just stuff in movement could be seen in the phenomena of life, or even life could be found there where physics only sees stuff in movement. Really, life is not just a matter of stuff. The way to find life is not dissecting a cell. That is a conception of a badly raised analysis, that what Whitehead called "badly raised concretization". Life is not a mere thing, life is a movement, a way to be, is election. Life is something characteristic, like the genius. We are looking for in the stuff something that is not inside it, but outside it, in another dimension, a design, an assembly of formative forces that use the physic-chemical dominion as a substrate for their original unfolding. Let us take only two examples.
First, let us consider the formation of the hand in the process of embryonic development. A small fin, a fragile fin forms itself in the beginning, with a fine skin that lets see us blood vessels. This fin made the biologists think that the development process reproduces the stages of the evolution of the species. However, what happens later with the fin? Does it develop fingers? No, the bones of the fingers are already in formation, under that skin, under that fragile meat. How fingers do form themselves, then? The cells of the fin, suddenly, start to destruct itself. The name of that self-destruction is "apoptosis". It seems that the fragile fin is going to disappear completely. How that compulsive death process could be stopped? It seems impossible. However, the process stops just when the form of the hand has been reached. How we explained this without thinking about an epigenetic training force that uses cells as its construction stuff?
Another example is the failure of the Human Genome Project. If we want to find in the genes the totality of information necessary to make a complete human organism, we must have about one hundred thousand genes. There are only thirty thousand genes. What happened with the rest of the information? Where are the other seventy thousand genes?
Now we know that, when DNA transcribed itself into ARN, the process does not finish. Specific enzymes cut the transcripted ARN in pieces and rejoin some of them. The final product is what the cell translates later into the language of proteins. Therefore, on the one hand, there is lacking information. On the other hand, a great part of the DNA does not contain information at all.
DNA no longer contains the secret wisdom to construct a living organism. DNA is just construction stuff, no more. Then, who is DNA maker?
The study of the human genome yielded another result, an unexpected, amazing result. If Theory of Evolution is correct, complex things would arise from simple ones. If this is true, we must be the strange result of the symbiosis of many viruses with bacteria. However, neither viruses nor bacteria have embryological development. In addition, origin of viruses already stands as an enigma for us. Viruses can only live inside complex living organisms, not in a free form in the outside. Once again we face the old and never solved paradox, that of the egg and the hen.
