TE stands for Tris and EDTA. The Tris buffers the water to prevent acid hydrolysis of the DNA/RNA. The EDTA chelates divalent cations that can assist in the degradation of RNA.

What role does papain play in the extraction of DNA?
Papain contains protease which is an enzyme that is responsible for removing the proteins in DNA. Which would be the histones, in which DNA is wrapped around
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 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.
Is the extraction of a liquid from a liquid solution is called liquid liquid extraction?
Yes, it is correct.

What is the role of NaCl in DNA precipitation?
roll of Na CL in DNA extraction
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.

stabilization of phenol against oxidation
What is the role of hot water bath in DNA extraction?
This question gave me cancer.
What is the role of heat in DNA extraction?
Heat anneals DNA strand i.e. separate two strands of DNA to build anti-codon to desired DNA strand
