Detailed explanation-1: -The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G)
Detailed explanation-2: -Definition. A unit of two bases in a molecule of DNA or RNA. 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-3: -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.
Detailed explanation-4: -Uracil (U) is one of the four nucleotide bases in RNA, with the other three being adenine (A), cytosine (C) and guanine (G). In RNA, uracil pairs with adenine.
Detailed explanation-5: -RNA is composed of four nucleotides: adenine (A), guanine (G), cytosine (C), and uracil (U).
