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

  1. Oxygen

  2. Adenine

  3. RNA

  4. Morula

The correct answer is: Adenine

Pyrimidine bases are an essential component of nucleic acids, which are responsible for the storage and transfer of genetic information. The other options, oxygen, RNA, and morula, all have a role in this process, with oxygen being an element necessary for chemical reactions, RNA being a type of nucleic acid, and morula being an early stage in the development of an organism. Adenine, on the other hand, is a purine base, not a pyrimidine base, and is not found in nucleic acids.
