what is DNA Extraction ?

DNA extraction is a process that used to purify DNA by using chemical or physical methods from a biological sample separating DNA from protein, cell membranes, and other cellular components. DNA extraction protocol involves lysis of membranes for DNA extraction, then separating DNA from impurities like proteins, and other substances.

What is DNA Extraction Principle?

DNA extraction involves lysis of cellular and nuclear membranes in order to extract DNA from within. This is followed by DNA separation from impurities, proteins, and other substances. General Stages of DNA Extraction are: Cell dissolution: lysis of cell and the nucleus to extract DNA into the buffer. Precipitation: removing the impurities and proteins from the sample. Purification: This final stage is done to get a completely pure DNA sample ready to be used. Note: the main steps remain similar among all DNA extraction methods.
