Enzyme to be used for isolation of DNA from fungal source in first step is

Options

  1. AProtease
  2. BCellulase
  3. CChitinase
  4. DLigase

Correct answer

C. Chitinase

Step-by-step solution

Since the DNA is enclosed within the membranes, we have to break the cell open to release DNA along with other macromolecules such as RNA, proteins, polysaccharides and also lipids. This can be achieved by treating the bacterial cells/plant or animal tissue with enzymes such as lysozyme (bacteria), cellulase (plant cells), chitinase (fungus). You know that genes are located on long molecules of DNA intertwined with proteins such as histones
