DNA Extraction - FORENSIC SCIENCE- function of liquid detergent in dna extraction method ,DNA extraction 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 science. DNA extraction is typically the first step in a longer laboratory process.The Basics of DNA Extraction – Alaska BioPREP Virtual TextbookThe three basic steps of DNA extraction are 1) lysis, 2) precipitation, and 3) purification. Step 1: Lysis. In this step, the cell and the nucleus are broken open to release the DNA inside and there are two ways to do this. First, mechanical disruption breaks open the cells. This can be done with a tissue homogenizer (like a small blender ...
