Statement A : Use of chitinase enzyme is necessary for isolation of DNA from fungal cells. Statement B : Fungal cell wall is made up of cellulose and chitinase is able to digest it.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
These enzymes degrade cell wall, plasma membrane degrading enzymes like lipase, etc. are also needed. Since yeast is a fungus and fungal cell with is made of chitin (fungal cellulose), isolation of DNA necessarily requires use of enzyme chitinase. Statement A is correct.
