DNA extraction is used in medical conditions investigation such as Down syndrome and cystic fibrosis. It is also helpful in case of identification if a person is a ... WebFor extraction of DNA, Tris- or TE-saturated phenol of a pH of approx. 7.8 is used. Phenol of this pH value suppresses partitioning of DNA into the organic phase and, therefore, both kinds of nucleic acids are isolated equally. Hence, for RNA isolation, pure water is used as solvent for phenol which then has a pH of about 4.8.
