Assertion (A) Adenine and guanine are present in RNA as purine bases. Reason (R) The base uracil is present in RNA. The correct option among the following is
- A \((A)\) is true, \((R)\) is true and \((R)\) is the correct explanation for \((A)\).
- B \((A)\) is true, \((R)\) is true but \((R)\) is not the correct explanation for \((A)\).
- C \((A)\) is true but \((R)\) is false.
- D (A) is false but (R) is true.
Answer & Solution
Correct Answer
(B) \((A)\) is true, \((R)\) is true but \((R)\) is not the correct explanation for \((A)\).
Step-by-step Solution
Detailed explanation
RNA contains four bases : The purines - adenine (A) and guanine \((G)\). The pyrimidines - cytosine (C) and uracil (U). The bases can interact via hydrogen bonds. So, (A) and (R) are true but (R) is not the correct explanation of (A).
