Detailed explanation-1: -In DNA, adenine always pairs with thymine (A-T), and guanine always pairs with cytosine (G-C). RNA is the same, except that adenine always pairs with uracil (A-U).
Detailed explanation-2: -The complementary base of adenine in RNA molecule is thymine.
Detailed explanation-3: -Adenine-uracil base pairs, or AU base pairs, are held together by 2 hydrogen bonds. Guanine-cytosine base pairs, or GC base pairs, are held together by 3 hydrogen bonds. The hydrogen bond donors and acceptors are labeled on the bases.
Detailed explanation-4: -G·U pairs have now been found in virtually every class of functional RNA, and have been shown to play many essential roles that are based upon the unique chemical and structural properties of the wobble pair.
