Provide an example of the nucleic acid bases.

The nucleic acid bases include adenine, guanine, cytosine, thymine and uracil.

Nucleic acid bases are the building blocks of DNA and RNA. Adenine (A), guanine (G), cytosine (C), thymine (T) and uracil (U) are the five types of nucleic acid bases. Adenine and guanine are purine bases, while cytosine, thymine and uracil are pyrimidine bases.

In DNA, adenine pairs with thymine and guanine pairs with cytosine, forming the base pairs that hold the two strands of the double helix together. In RNA, uracil replaces thymine and pairs with adenine.

The sequence of nucleic acid bases in DNA and RNA determines the genetic information of an organism. Mutations in the sequence can lead to genetic disorders and diseases.

Nucleic acid bases are also involved in various cellular processes, such as DNA replication, transcription and translation. They are essential for the proper functioning of cells and the transmission of genetic information from one generation to the next.

In conclusion, nucleic acid bases are the fundamental units of DNA and RNA, and play a crucial role in the genetic information and cellular processes of all living organisms.
