Assertion : Use of chitinase enzyme is necessary for isolation of DNA from yeast cells but not in case of Spirogyra.
Reason : Fungal cell wall is made up of fungal cellulose or chitin.

Options

A. Both A and R are true and R is the correct explanation of A
B. Both A and R are true and R is not the correct explanation of A.
C. A is true but R is false.
D. A is false but R is true.

Answer

A

Explanation

For the isolation of DNA, the cell wall needs to be ruptured. The cell wall of fungi is made up of chitin and hence chitinase is used while cell wall of Spirogyra is made up of cellulose, hence cellulase enzyme would be used.
