Zoology - Biotechnology - Principles and Processes Question with Solution | TestHub

For extracting DNA from a cell it is first cut and opened by a lysing enzyme that degrades cell wall and cell membrane. For plant cells, the cell wall is degraded by cellulase and pectinase. The fungal cell wall is made up of chitin, thus chitinase is used. The bacterial cell wall is degraded by lysozyme and the animal cell membrane is degraded by the enzyme proteinase K.
