Question

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

Open in App

Solution

Plant cells have cellulose in their cell wall which can be degraded using the enzyme cellulase for isolating the genetic material DNA. On the other hand, animal cell wall does not contain cellulose. Hence, cellulase is not required for isolating DNA.
