because it can break through the membranes to get to the DNA
The most likely function of the extraction buffer would be to maintain an isotonic environment that favors the stability of the protein. An isotonic solution mimics the ionic environment if the cell and therefore would keep the protein in a stable form during the process of extraction. Proteins undergo changes in different ionic environments (different pH's) and it is essential to keep them in a stable form.
When small amounts of acid or base are added to a buffer solution, the buffer functions to keep the pH from changing.
Solutions that resist change in pH when added to a strong acid or base are known as buffer solutions.
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.
The buffer can keep the pH stable when small amounts of acid or base are added. - NOVA
The detergent was added because it breaks open the cells by destroying fatty membranes that enclose the cell, thus releasing the DNA into the solution.
Extraction Buffer is used to maintain pH of the solution.which prevents denaturation of DNA.
The word detergent is used instead of soap in a DNA extraction buffer. Detergent is used to create a hydrophobic environment that favors the precipitation of proteins. Proteins are one of two major contaminants in DNA extraction (the other major contaminant being RNA). When protein precipitate, they can be separated by centrifugation and the DNA isolation procedure can continue.
ethyl or grain
The buffer AP1 is vital in DNA extraction as it acts as a cleanser to break up the lipids surrounding the cellular membrane. The buffer also maintains the right environment for the DNA so it is not damaged during the extraction process.
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.
It helps break the nuclear membrane of the cell. Detergent containing the compound SDS ( sodiumdodecyl sulfate) is used to break down and emulsify the fat and proteins that make up a cell membrane.

It is usually added during an extraction in order to make the solution alkaline. Often times, this aids in the efficiency of the extraction.
