There is no ‘one’ procedure for extracting DNA from the whole blood of both mammals and birds, since each species has a unique property that require different methods to release its own DNA. Therefore, to obtain genomic DNA, a universal, rapid, and noncostly method was developed. A very simple biological basis is followed in this procedure, in which, when the blood is placed in water, it rapidly enters the RBCs by osmosis and causes cells to burst by hemolysis. The validity of extracting genomic DNA was confirmed by several molecular biological experiments. It was found that this method provides an efficient and versatile alternative for extracting bulk amounts of highly-qualified DNA from the blood of a wide range of species. This is the first manuscript that describes use of distilled water as the only eliminator of RBCs among all other known DNA extraction techniques.
