Given below are two statements marked Assertion and Reason. Assertion: RNAi technique is applied to plants and animals to protect them from pest infestation. Reason: This technique inhibits the expression of certain genes in pests.
Show Hint
RNAi = Gene Silencing. Always look for this link in Biotech questions.
Both Assertion and Reason are true and Reason is the correct explanation for Assertion.
Both Assertion and Reason are true but Reason is not the correct explanation for Assertion.
Assertion is true and Reason is false.
Both Assertion and Reason are false.
Show Solution
The Correct Option isA
Solution and Explanation
The question involves evaluating the truthfulness of the Assertion and the Reason related to the RNA interference (RNAi) technique in biological applications, specifically dealing with pest infestations.
Understanding the Assertion: The assertion states that the RNAi technique is applied to both plants and animals to protect them from pest infestation. This is a true statement. RNAi is a biological process where RNA molecules inhibit gene expression or translation by neutralizing targeted mRNA molecules. In agriculture, RNAi is used to develop pest-resistant plants by targeting pest-specific genes, thereby reducing the need for chemical pesticides.
Understanding the Reason: The reason given is that the RNAi technique inhibits the expression of certain genes in pests. This statement is also true. The mechanism of RNAi involves silencing specific genes in pests, which disrupts their normal physiological processes, ultimately protecting the target organism (plant or animal) from pest attacks.
Evaluating the Explanation: We need to determine if the Reason correctly explains the Assertion. The reason effectively explains why the RNAi technique helps protect the plants and animals from pests—by inhibiting gene expression in those pests. This indicates that the Reason is not only true but also the correct explanation for the Assertion.
Conclusion: Given that both the Assertion and the Reason are true, and the Reason correctly explains the Assertion, the correct option is: "Both Assertion and Reason are true and Reason is the correct explanation for Assertion."
