It solubalize lipids and protiens to remove them from DNA
Phenol and chloroform are very hydrophobic and are used to remove non-polar bio- molecules (proteins, fragments of membranes, lipids etc) in the extraction.
The actual role of phenol chloroform isoamyl alcohol in a plasmid DNA extraction is to purify the DNA. The alcohol will act in part as a detergent.
Chloroform denaturizes the proteins and facilitates the separation of the aqueous and organic phase. If needed the extraction with chloroform is performed two or three times to completely remove the impurities from aqueous layer..
Did u mean function of chloroform isoamyl alcohol in DNA extraction? Chloroform isoamyl alcohol is a type of detergent. It binds to protein and lipids of cell membrane and dissolve them. By this it will disrupt the bonds that hold the cell membrane together and cause it to breakdown. It then form complexes with these lipids and proteins, causing them to precipitate out of solution. Note that lipids and proteins are non-aqueous compound and DNA/RNA are aqueous compound. The detergent binds to non-aqueous compound.
Chloroform causes proteins to become denatured and become soluble in the organic phase or interphase, while nucleic acids remain in the aqueous phase.

In a DNA extraction, the purpose of a buffer is to solubilize DNA as well as RNA. Because of this, it prevents the DNA for degrading.
