they are insoluble together. They are colorless.
No they don't react together. but phenol is soluble in CHCl3.
Chloroform is a solvent that helps to separate the three phases in phenol-chloroform extraction by disrupting the interactions between the biomolecules. RNA, DNA, and proteins have different affinities for phenol, chloroform, and water, leading to their partitioning into separate phases based on their solubility. Chloroform enhances the separation by forming distinct layers that can be easily separated, allowing for the isolation of the desired biomolecules.
Phenol chloroform isoamyl alcohol is used in plasmid DNA extraction to separate DNA from proteins and other contaminants. Phenol denatures protein structures, allowing them to be separated from the DNA. Chloroform and isoamyl alcohol are used to further purify the DNA by removing residual phenol and debris.
Phenol chloroform isoamyl alcohol helps to separate proteins and lipids from DNA during extraction. Phenol denatures proteins, chloroform aids in partitioning DNA, while isoamyl alcohol prevents foaming. This combination allows for efficient extraction of DNA from biological samples.

To ensure pure DNA extraction using the phenol-chloroform-isoamylalcohol method, it is crucial to carefully perform the organic phase separation step, separating the DNA-containing aqueous phase from the phenol-chloroform layer. Additionally, thorough washing of the DNA pellet with ethanol to remove any residual contaminants is recommended. Finally, using molecular biology-grade reagents and sterile technique throughout the procedure can help minimize contamination.
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.
Phenol chloroform isoamyl alcohol is used in plasmid isolation to effectively separate nucleic acids into aqueous and organic phases. The phenol denatures proteins and inactivates nucleases, chloroform aids in the separation of the phases, and isoamyl alcohol prevents foaming during mixing. Overall, this reagent allows for the extraction and purification of plasmid DNA from other cellular components.
You can quickly confirm which layer is water and which is chloroform by adding a few drops of water to a test tube containing the layers. Water will mix with the layer that is water, causing it to become more transparent. Chloroform will not mix with water and remain as a separate layer.
The chloroform layer will turn purple or violet in color due to the formation of the organic bromine compound when NaBr reacts with Cl2 in water and then extracted into chloroform during the test.
