Question

Assertion: Chitinase is the lysing enzyme used to open up the fungal cells to get DNA.
Reason: This enzyme dissolves the fungal cell wall.

• A. Both assertion and reason are true and the reason is the correct explanation of the assertion
• B. Both assertion and reason are true but the reason is not the correct explanation of the assertion
• C. Assertion is true but the reason is false
• D. Both assertion and reason are false

Answer 1

The correct option is A Both assertion and reason are true and the reason is the correct explanation of the assertion

Different cell types take different enzymes to break open.
One of the most distinguishing features of plant cells is the presence of a cell wall. The plant’s cell wall is primarily made of cellulose, Cellulose is a long polymer of hundreds of glucose molecules.Cellulase is the enzyme that breaks down cellulose into its monosaccharide units.

Likewise, fungi also contain a cell wall, which is made up of a long polymer chain of N-acetylglucosamine, called chitin. This is the primary component of the cell wall of the fungi and exoskeleton of some arthropods like crustaceans, insects etc. To break the polypeptide of N-acetyl glucosamine into its constituents, the enzyme chitinase is used.
