Why is the enzyme cellulase needed for isolating genetic material from plant cells and not form the animal cells?
Why is the enzyme cellulase used for isolating genetic material from plant cells but not for animal cells?

उत्तर
Plant cells have a cell wall made up of cellulose, whereasanimal cells lack cell wall and do not contain cellulose. Therefore, the enzyme cellulase is needed for isolating genetic material from plant cells only.
