Abstract
All creatures in the earth move all the time due they have certain energy which continually produced in them bodies. References(11 and 15)show that ATP and other like nucleotides are responsible for producing this energy but how this specific moleculeproduce energy while thousands chemical molecules do notdo that!In another hand, cell'sdivision is so important process in the earth, it represents life's basic phenomenon, it responsible for; Reproduction, Repair and Growthof all creaturesin the world. Then without understanding scientific basics of this phenomenon,it is impossible to understand howhumans and other creatures form, how they grow up, and how they repair thosebodies!It highly obvious that there is no clearscientific vision about above most importantphenomenain the earth, for this, in this research a full survey depending on chemistry principles was done on known procedures of DNA extraction processes. In addition, it contains chemical explanation for DNA's identification techniques; U.V.-Visible,Electrophoresis and N.M.R spectroscopy.Finally, the truth moment of this research representsall above surveys which includedDNA's samples that extracted in biology department. All these indicated one scientific fact that DNA extraction processes that widely used for long time ago by many researchers produce unsaturated fatty acidsdo notproduce DNA or nucleotidesmolecules. Therefore, all theories that depended on these extractions processes are incorrect. Understanding of different Cells functions depending on facts and good evidences lead this research to explain another important conceptsuch as;Fertilization process, identities of different viruses and their right treatment,the reason of obesityand its right treatment...etc.Depending on;Chemistry science, facts and excellent evidences,this research givesfull explanations about above so important phenomenaand concepts. It believesthat chemistry can solve more than these and it able to explainmost important phenomena in the earth. In fact, Chemistry touch is so necessary for explainingmost important phenomena in the earth
