Detailed explanation-1: -Answer: Explanation: Adenine pairs with Thymine (DNA) or Uracil (RNA) Guanine pairs with Cytosine.
Detailed explanation-2: -In RNA, uracil pairs with adenine. In a DNA molecule, the nucleotide thymine (T) is used in place of uracil.
Detailed explanation-3: -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-4: -Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together.
Detailed explanation-5: -The base pairing of guanine (G) and cytosine (C) is just the same in DNA and RNA. So in RNA the important base pairs are: adenine (A) pairs with uracil (U); guanine (G) pairs with cytosine (C).
