Explanation:
Detailed explanation-1: -Answer: Explanation: Adenine pairs with Thymine (DNA) or Uracil (RNA) Guanine pairs with Cytosine.
Detailed explanation-2: -The two strands are held together by hydrogen bonds between pairs of bases: adenine pairs with thymine, and cytosine pairs with guanine.
Detailed explanation-3: -It is important to note that in RNA (RiboNucleic Acid), adenine pairs with uracil because RNA molecules do not contain any thymine. The shape of the uracil molecule is very similar to thymine; the only difference is that uracil (formula C4H4N2O2 C 4 H 4 N 2 O 2 ) is missing a methyl group (-CH3 C H 3 ).
