ABSTRACT:
Disclosure is a method of separately recovering deoxyribonucleic acid and ribonucleic acid from a biological sample solution. They are separated and recovered from a single biological sample by controlling pH values, temperature, and/or concentration of cationic ions of a nucleic acid sample solution containing a caotropic agent. It is possible to easily and safely separate and recover deoxyribonucleic acid and ribonucleic acid from the single biological sample.
