The correct Answer is:
### Step-by-Step Solution:
1. **Understanding the Question**: The question asks about "Deoxyguanosine" and what it is classified as in the context of molecular biology.
2. **Identifying the Types of Genetic Material**: There are two main types of genetic material: DNA (Deoxyribonucleic Acid) and RNA (Ribonucleic Acid).
3. **Differentiating Between DNA and RNA**:
- DNA contains a sugar called deoxyribose.
- RNA contains a sugar called ribose.
- The key difference is that deoxyribose lacks one oxygen atom that ribose has.
4. **Understanding Nucleotides and Nucleosides**:
- A nucleotide is composed of a nucleoside and a phosphate group.
- A nucleoside consists of a sugar (deoxyribose in the case of DNA) and a nitrogen base.
5. **Identifying the Components of Deoxyguanosine**:
- Deoxyguanosine is a nucleoside that consists of deoxyribose sugar and the nitrogen base guanine.
- It does not have a phosphate group, which means it is not a nucleotide.
6. **Conclusion**: Since deoxyguanosine is made up of deoxyribose and guanine, it is classified as a **nucleoside of DNA**.
### Final Answer:
Deoxyguanosine is a **nucleoside of DNA**.
