In a basis of that, what we name as common sense, there is the principle, according to which, we prefer, from many probable explanations other things being equal, the simplest explanation. And it, basically, is correctly because process of cognition occurs from simple to complex. But, unfortunately, in parallel sciences this principle is observed very seldom. So, for example, two parallel sciences – the physics and the chemistry, investigate the same object – substance. Thus, the physicists should give correct model of a structure of atoms, whereupon the chemists, using this model, should give correct model of a structure of molecules, including, the correct spatial structure of the elementary cell of life, i.e. a structure of the molecule of desoxyribonucleic acid (DNA). After that chemists and physicists should give the unequivocal answer to a question – what is LIFE. It is the main question for our civilization. … In such a way the small article (4 pages) "Spinal cord of DNA-molecule" begins. Now the server, where there is my web-site, is broken, therefore I have placed this article in my small homepage: http://www.sinor.ru/~polytron/Spinal_cord_of_DNA-molecule_e.htm http://www.sinor.ru/~polytron/Spinal_cord_of_DNA-molecula_r.htm As soon as the server will be repaired, I shall place the article in my web-site in PDF-format.
