What is used to remove proteins from the mixture of released macromolecules?

Options

  1. AChitinase
  2. BCellulase
  3. CRibonuclease
  4. DProtease

Correct answer

D. Protease

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 interwined with proteins such as histones. The RNA can be removed by treatment with ribonuclease whereas proteins can
