AIIMS 2018 Zoology RNA Interference Assertion Reason Question
Assertion: We can develop nematode resistant plants by RNA interference technology. Reason: Secondary metabolites can be produced by genetic engineering in plants.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
Option B is correct because the assertion that RNA interference (RNAi) technology can be used to develop nematode-resistant plants is true; RNAi allows for the silencing of specific genes in nematodes, thereby enhancing plant resistance. However, the reason provided, which states that secondary metabolites can be produced by genetic engineering in plants, does not directly explain how RNAi contributes to nematode resistance, making it an unrelated fact.
Option A is incorrect because, while both statements are true, the reason does not explain the assertion. Option C is incorrect as the assertion is true and the reason is also true, thus ruling out the possibility of the reason being false. Option D is incorrect since both statements are indeed true.
