Detailed explanation-1: -The two strands are held together by hydrogen bonds between pairs of bases: adenine pairs with thymine, and cytosine pairs with guanine.
Detailed explanation-2: -Final answer: In DNA the complementary bases are adenine and thymine, guanine, and cytosine.
Detailed explanation-3: -Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together.
Detailed explanation-4: -In DNA, adenine always pairs with thymine (A-T), and guanine always pairs with cytosine (G-C).
Detailed explanation-5: -either of the nucleotide bases linked by a hydrogen bond on opposite strands of DNA or double-stranded RNA: guanine is the complementary base of cytosine, and adenine is the complementary base of thymine in DNA and of uracil in RNA.
