Role of phenol in DNA isolation?

Purification of the DNA sample. Phenol is carbolic acid and is used to dissolve proteins and other cellular debris associated with the DNA being prepared for analysis.


What is the principle of DNA isolation using phenol chloroform method?

Phenol chloroform extraction is the oldest and still widely followed method for the isolation and extraction of DNA from plant and animal cells. The phenol, chloroform (and also isoamyl alchohol) are added in a specific ratio of 25: 24:1.Phenol: Phenol dissolves the organic impurities, like proteins etc.chloroform: Provides density to phenol so that it settles below water during phase separation.Isoamylalchohol: Used to prevent phosgene from reaction of chloroform with air.The Phenol:Chloroform:Isoamylalchohol (PCI) solution is added to the cell extract after removal removal of debris. After proper mixing, cetrifugation is done to separate the phases. Two phases are formed: The upper, the aqueous phase that contains DNA, the lower phase, that phenol phase, that contains organic impurities. Thus two phases are separated by a very clearly defined boundary of coagulated proteins.The aqueous phase is precipitated and then the DNA could be pelleted after rounds of purifications.


Why use chloroform in DNA isolation?

DNA is soluble in chloroform more than water. So we use it.


What materials do scientists typically use when extracting DNA?

phenol,chloroform,isoamyl alcohol,ethanol,CTAB reagent,Na acetate etc.. but nowadays, they use kits for any kind of DNA isolation, which makes their job easier.


What is the function of buffered phenol chloroform in DNA extraction?

Phenol and chloroform are very hydrophobic and are used to remove non-polar bio- molecules (proteins, fragments of membranes, lipids etc) in the extraction.
