Question

is used to break down the cell membrane of a cell.

• A. DNA ligase
• B. Detergent
• C. Cellulase
• D. Polymerase

Answer 1

The correct option is B Detergent

The hydrophobic end of the phospholipid bilayer stays away from the water. This avoids the dissolution of cell membrane in water. But the detergent can bind to the hydrophobic end of the cell membrane and form a solution with water, thus breaking the cell membrane barrier.
Cellulases are used to breakdown cell wall of plant cells. The main function of DNA polymerase is to synthesize DNA. A ligase facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond.
