DNA isolation is a process of purification of DNA from sample using a combination of physical and chemical methods.The first isolation of DNA was done in 1869 by Friedrich Miescher. Currently it is a routine procedure in molecular biology or forensic analyses. Breaking the cells open, commonly referred to as cell disruption or cell lysis, to expose the DNA within. 2  This is commonly achieved by chemical and physical methods-blending, grinding or sonicating the sample. 3  Removing membrane lipids by adding a detergent or surfactants which also serves in cell lysis.
Article Summary: DNA extraction is the process in which DNA is isolated from other cellular components through certain procedures. It has its applications in forensics.... 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.el Box is another machine which separates the sequences of DNA in the gel. An electric current is used for this purpose. In the end, centrifugation separates the DNA from the solution through spinning. Purpose of DNA Extraction:- Extraction of DNA is an important step in the diagnosis use.
