# Methods of DNA Isolation DNA isolation is one of the fundamental laboratory procedures used in molecular anthropology, genetics, forensic anthropology, population studies and biological research. DNA, or deoxyribonucleic acid, contains hereditary information and can be obtained from various biological materials such as blood, saliva, buccal cells, hair roots, bone, teeth and other tissues. In anthropological research, DNA isolation is particularly important because it provides genetic material for studying human variation, population history, biological relationships, migration, ancestry and evolutionary processes. The basic objective of DNA isolation is to separate DNA from cells and remove proteins, lipids, carbohydrates, RNA and other cellular components while preserving the integrity of the DNA. Several methods are available, depending upon the type and quantity of biological material, the quality of DNA required and the facilities available in the laboratory. Two commonly used methods are the organic solvent extraction method and the silica-based column method. The organic solvent extraction method, commonly known as the phenol-chloroform method, is a traditional and widely used technique for obtaining relatively pure genomic DNA. It is based on the differential solubility of DNA, proteins and other cellular substances in aqueous and organic phases. The method begins with the collection of an appropriate biological sample. Blood, buccal cells, tissue or other cellular material may be used. The cells are first subjected _________ ________ _______ _______ ______ ____ _______ ____ __________ _____ ________.
