AIIMS 2014 Botany Nucleic Acids Properties MCQ Question
Assertion DNA is more stable while RNA is more reactive. Reason DNA was first discovered by Watson and Crick (1953).
Both Assertion and Reason are true and Reason is the correct explanation of Assertion
Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion
Assertion is true but Reason is false
Both Assertion and Reason are false
Correct Answer
Detailed Explanation
The correct answer is C because the assertion that DNA is more stable and RNA is more reactive is true due to the structural differences between the two nucleic acids; DNA has a deoxyribose sugar and a double-helix structure, making it more resistant to hydrolysis, while RNA contains ribose and is single-stranded, making it more prone to chemical reactions. However, the reason given, that DNA was first discovered by Watson and Crick in 1953, is false; they elucidated the structure of DNA, not its discovery, which was made earlier by others.
