DNA Extraction and Gel Analysis - EG1003 Lab Manual

To aid in precipitating the DNA, alcohol is added since it cannot dissolve DNA. A translucent white substance will begin to form at the top; this is DNA. Once it is thick enough, it can be spooled out. This simple procedure is a rough extraction process that needs further purification before it can be successfully run on a gel for analysis.

What is the purpose of detergent in DNA extraction? - Quora

Answer (1 of 3): Cell walls are made of lipids, a kind of fat. Detergent breaks down that fat, allowing DNA to be extracted.
