Q. Which among the following mixtures would kill the mice in Griffith’s transformation experiment? (A) Heat killed S-strain + R-strain (live) + DNase (B) Heat killed S-strain + R-strain (live) + RNase (C) Heat killed S-strain + R-strain (live) + Protease Choose the most appropriate option.
A) Only (A)
B) (A), (B) and (C)
C) (B) and (C)
D) (A) and (C)
Explanation
DNase enzyme inhibits transformations, thus the mice would remain alive. However, RNase and protease did not affect transformation, therefore, the mice would get killed in case of (I) and (III).
