DNA extraction protocols are those of Dellaporta et al. 1983 and Saghai Maroof et al.,1984 along with many others that are modifications of the components of these protocols to suit a particular tissue type or downscaling them for miniprep. In addition to these basic protocols, a panorama of DNA isolation kits based on either anion exchange. DNA extraction is a procedure of isolating the DNA from other cellular components for the molecular or forensic analysis. Usually a machine is used to extract DNA from the cell that is called as Bead Beater. It breaks the cell and extracts the DNA from it. Gel Box is another machine which separates the sequences of DNA in the gel Chelex Extraction • The Chelex extraction process denatures double stranded DNA and yields single stranded DNA, and thus cannot be used for the RFLP procedure. • It is advantageous for PCR-based typing methods because it removes inhibitors of PCR and can be done in a single tube, which reduces the potential for laboratory-induced.
