Answer:

(d) cytosine and guanine

Answered by topwriters

(a) cytosine and thymine

Explanation:

The purines in DNA are adenine and guanine, the same as in RNA. The pyrimidines in DNA are cytosine and thymine; in RNA, they are cytosine and uracil. Purines are larger than pyrimidines because they have a two-ring structure while pyrimidines only have a single ring.

Option A is the answer.
