There are three basic steps in a DNA extraction, the details of which may vary depending on the type of sample and any substances that may interfere with the extraction and subsequent analysis. * Chelate divalent cations such as Mg2+ and Ca2+ to stop dnase enzymes functioning and degrading the DNA * Break open cells by grinding or sonication, and remove membrane lipids by adding a detergent. * Precipitate DNA in cold ethanol or isopropanal, DNA is insoluble in alcohol and clings together; this step also removes salt.
how to make sodium citrate in 10% ethanol for DNA extraction
The salt neutralizes the DNA's negative charge with its positive charge while the DNA precipitates.
removal of polyphenols
No-DNA exists in a microscopic level, you can't obtain it using a blender.
It plays a role.

DNA extraction from bacteria can be achieved in various ways. Yeast is the best resource to extract the DNA bacteria from using extreme rapid extraction method.
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.
Trichloroacetic acid is used for precipitation of the DNA during its extraction.
Extraction Buffer is used to maintain pH of the solution.which prevents denaturation of DNA.
the purpose of grinding any substance during dna extraction is cell loosening.
We can not extract DNA from RBCs as they are without nucleus. only the source of DNA extraction is Leukocytes, RBCs are not good source of extraction but we can extract DNA from immature RBCs.
To achieve precipitation DNA.
The 200-400 mesh size is best for DNA extraction. The smaller sizes are usually used for metal ion extraction.
