Guanine is an example of:
Guanine is an example of:
- A. Nucleotide
- B. Nucleoside
- C. Purine base
- D. Pyrimidine base
Step-by-step solution
Guanine is a nitrogenous base found in DNA and RNA. It has a double-ring structure characteristic of purines, making it a purine base. It is not a nucleotide (which additionally includes a sugar and phosphate) nor a nucleoside (base + sugar). Therefore, it is classified as a purine base.
