Two statements, Assertion and Reason are given. Choose the correct option from the following.
Assertion: In the secondary structure of RNA, double helix structure is formed.
Reason: In the double structure of RNA, two nucleic acid chains are wound about each other and held together by hydrogen bonds between pairs of bases
- A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
- B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
- C Assertion is incorrect but Reason is correct.
- D Assertion is correct but Reason is incorrect.
Answer & Solution
Correct Answer
(D) Assertion is correct but Reason is incorrect.
Step-by-step Solution
Detailed explanation
Assertion is correct: RNA is single-stranded, but its secondary structure involves the strand folding back on itself to form localised double-helical regions (e.g., stem-loops in tRNA, hairpin loops). Reason is incorrect: The double-helical regions in RNA are formed by…
