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.
Deoxyribonucleic acid (DNA) isolation is an extraction process of DNA from various sources. Methods used to isolate DNA are dependent on the source, age, and size of the sample.Despite the wide variety of methods used, there are some similarities among them.solation of DNA is needed for genetic analysis, which is used for scientific, medical, or forensic purposes. Scientists use DNA in a number of applications, such as introduction of DNA into cells and animals or plants, or for diagnostic purposes. In medicine the latter application is the most common.
