How DNA Extraction Is Different in Plants - Bitesize Bio

The most common method is grinding with a mortar and pestle. Tissue is first frozen in liquid nitrogen and then ground into a powder. Care must be taken to do this quickly, so the tissue isn’t allowed to warm too much. If the tissue becomes warm, then the
