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: -Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The binding of these base pairs forms the structure of DNA .
Detailed explanation-3: -Listen to pronunciation. (bays payr) Two nitrogen-containing bases (or nucleotides) that pair together to form the structure of DNA. The four bases in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).
Detailed explanation-4: -The Adenine-Thymine base pair is held together by 2 hydrogen bonds while the Guanine-Cytosine base pair is held together by 3 hydrogen bonds.
Detailed explanation-5: -Answer and Explanation: The correct pairing for nitrogenous bases is (c.) adenine-thymine; guanine-cytosine in DNA and (a.) adenine-uracil; guanine-cytosine in RNA.
