Q. Assertion: Transforming substance in Griffith experiment were not protein or RNA. Reason: Digestion with DNase inhibits transformation.
A) Both assertion and reason are true and reason is the correct explanation of assertion.
B) Both assertion and reason are true but reason is not correct explanation of assertion.
C) Assertion is true, but reason is false.
D) Both assertion and reason are false.
Explanation
In transforming experiment, digestion through RNase and proteases did not inhibit transformation thus, RNA and protein were not transforming substances. However, digestion through DNase inhibits transformation, indicating that DNA caused the transformation of R-strain.
