The main function of chloroform is to protect genomic DNA during a catastrophe. Chloroform increases the efficiency of phenol to denature the protein. Here, chloroform allows proper separation of the organic phase and aqueous phase and keeps DNA protected into the aqueous phase. See more As we said earlier, phenol-chloroform isoamyl alcohol relies on the principle of liquid-liquid extraction of biomolecules. It denatures the protein part and separates the genomic DNA into a soluble phase. To understand it … See more The technique becomes more aggressive when the isoamyl alcohol is used along with phenol and chloroform therefore the technique is often known as PCI DNA extraction. The in-depth role of three major constituents is … See more We cannot use phenol directly, we have to prepare saturated phenol before proceeding further.
