Which of the following is not a pyrimidine base found in nucleic acids?

  1. Adenine

  2. Thymine

  3. Uracil

  4. Cytosine

The correct answer is: Adenine

Adenine is a purine base, rather than a pyrimidine base, and is found in both DNA and RNA. Option B, thymine, is a pyrimidine base and is found in DNA. Option C, uracil, is also a pyrimidine base but is found in RNA instead of DNA. Option D, cytosine, is another pyrimidine base found in both DNA and RNA. Therefore, option A, adenine, is the only incorrect answer as it does not fit the criteria of being a pyrimidine base found in nucleic acids.
