The RNA which base pairs with the adenine in DNA are Thymine.
Thymine
Explanation:
When nitrogenous base creates hydrogen bond with each other. It commonly shows the base pairs occurrence. Each of the bases have a particular partner like adenine with thymine in DNA, guanine-cytosine and adenine-uracil in RNA.
Even though, uracil and thymine seems to have similar structures to form base pairs in RNA, uracil, a live tissue inside RNA. Whereas, thymine, a compound or nucleic acid's part.
