Extraction and purification of DNA are the first steps in the analysis and manipulation of DNA that allow scientists to detect genetic disorders, produce DNA fingerprints of individuals, and even create genetically engineered organisms that can produce beneficial products such as insulin, antibiotics, and hormones.
DNA extraction is done by three methods: In organic extraction, phenol and chloroform are used to create on organic phase in which cells are lysed and DNA is freed. The DNA remains in the aqueous phase. Ethyl alcohol is used to precipitate the DNA. In the inroganic methos, NaCl and EDTA are used for cell lysis.Following this, an approach similar to the organic method is followed. In solid state extraction, DNA is first precipitated in the presence of high slat and low pH conditions.The precipitated DNA is then adsorbed on to a filter membrane surface.he DNA remains in the aqueous phase. Ethyl alcohol is used to precipitate the DNA. In the inroganic methos, NaCl and EDTA are used for cell lysis. Following this, an approach similar to the organic method is followed.
