Q. Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R. Assertion A: In recombinant DNA technology, lysozyme is used for disrupting bacterial cells while cellulase is for plant cells. Reason R: Isolation of genetic material needs disruption of cells. In the light of the above statements, choose the most appropriate answer from the options given below:
A) A is not correct but R is correct
B) Both A and R are correct and R is the correct explanation of A
C) Both A and R are correct but R is not the correct explanation of A
D) A is correct but R is not correct
Explanation
[Solution from source] To isolate DNA the cell wall must be broken: lysozyme digests the bacterial cell wall and cellulase digests the plant cell wall. R explains why these enzymes are used. Answer (2).
