The Pyrimidine bases in DNA are:

  1. A
    Adenine and Guanine
  2. B
    Thymine and Adenine
  3. C
    Cytosine and Guanine
  4. D
    Thymine and Cytosine

Solution & Step-by-step Explanation

Nitrogenous bases in DNA are categorized into two classes:
* Purines: Adenine (A) and Guanine (G), which possess a double-ring structure.
* Pyrimidines: Thymine (T) and Cytosine (C), which possess a single-ring structure. (Note: Uracil replaces Thymine in RNA).
