to separate two layer.DNA is insoluble in alcohol so it will floats up and all other cell components will precipitate at the bottom of the test tube.CIA also helps to isolate the CTAB solution so it will be easy to obtain the DNA.

What is the function in the following reagents used in the extraction and precipitation of DNA?
to extract the DNA from the solution, isopropyl alcohol is mixed with the DNA solution to precipitate the same.
Can you use spirit for DNA precipitation?
Several DNA isolation protocols recommend the use of either ethyl or isoamyl alcohol for the precipitation step
What is the function of 2-propanol in DNA extraction?
To achieve precipitation DNA.
Can iso amyl alcohol replace phenol in DNA extraction?
No
What is the function of dithiothreitol in DNA extraction?
DTT is the reducing agent for thiolated DNA
Role of phenol chloroform isoamyl alcohol in plasmid DNA 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.
What is the function of chloroform isoamyl alcohol?
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.
What is the function of the alcohol in DNA extraction?
DNA is not soluble in isopropyl alcohol. It will precipitate out when you add this solvent. Once out of solution you can centrifuge it down and collect the pellet of DNA.

Function TE in extraction DNA?
chelating Mg2+

What is the function of chloroform in DNA extraction?
It solubalize lipids and protiens to remove them from DNA
What is the function of CL buffer in DNA extraction?
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.
What is the function of ascorbic acid in DNA extraction?
removal of polyphenols
