So as to maintain a favourable pH for the isolated DNA
In an elution buffer at room temperature.
Buffer AL is used in DNA extraction and causes cell lysis to expose the DNA. Buffer AL is used during DNA isolation using QIAamp and DNeasy protocols. Buffer AL is stable for 1 year when stored closed at room temperature (15-25°C). Preparation of Buffer AL/E is as such: Volume of Buffer AL (ml) Volume of 96-100% ethanol (ml) Bottle size (ml) 33 35 100 108 114 250 162 171 500 216 228 500
Extraction Buffer is used to maintain pH of the solution.which prevents denaturation of DNA.
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.
Plasmid isolation has a step called washing step that carried out in the column in which the plasmid DNA are already bind. There are two wash solution, first one endo wash buffer that wash the traces of bacterial membrane remnants such as LPS. Wash buffer two has ethanol wash off any protein contaminants present on the column. These wash steps ensure the purify of isolated plasmid DNA.
In an elution buffer at room temperature.
Tris EDTA buffer inhibits nucleases that will degrade the DNA, by chelating cations required by the enzymes. Phosphate buffer offers no such protection against degradation.
Dna is soluble in water
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.

Extraction Buffer is used to maintain pH of the solution.which prevents denaturation of DNA.
DNA was first isolated in 1869.
TE buffer is a often used as a buffer solution in molecular biology, mainly in procedures involving DNA or RNA. The purpose of TE buffer is to solubilize DNA or RNA, while protecting it from degradation.
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.
DNA is tightly wrapped into chromosomes, and stored within the nucleus of each cell
