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

Options

  1. A(A) is true, (R) is true and (R) is the correct explanation for (A) .
  2. B(A) is true, (R) is true but (R) is not the correct explanation for (A) .
  3. C(A) is true but (R) is false.
  4. D(A) is false but (R) is true.

Correct answer

B. (A) is true, (R) is true but (R) is not the correct explanation for (A) .

Step-by-step solution

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).
