Explanation:
Detailed explanation-1: -Four different types of nitrogenous bases are found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G).
Detailed explanation-2: -There are four nucleotides, or bases, in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T).
Detailed explanation-3: -The four bases in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). These bases form specific pairs (A with T, and G with C).
Detailed explanation-4: -Hence, Adenine, Guanine, and Cytosine are common to both DNA and RNA.
Detailed explanation-5: -The nitrogen bases are held together by hydrogen bonds: adenine and thymine form two hydrogen bonds; cytosine and guanine form three hydrogen bonds.
