DNA is used for genetic engineering processes. But this DNA should be in pure form Hence the first is used for genetic engineering processes. But this DNA should be in pure form and so it need to be first removed. The cell is broken first so that DNA alongwith RNA, Chromatin material from the nucleus is obtained. Breakdown of the cell require enzymes and these enzymes are very specific to organisms. Cellulase is used to brea cells of plants while chitinase is used break fungal cell walls and Lysozyme is used to break bacterial cell walls.
