The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Nucleosome**: A nucleosome is a structural unit of chromatin in eukaryotic cells. It plays a crucial role in packaging DNA into a more compact, dense shape. 2. **Components of Nucleosome**: The nucleosome is primarily composed of DNA wrapped around a core of histone proteins. 3. **Histone Proteins**: Histones are positively charged proteins that bind strongly to negatively charged DNA. They help in the organization and compaction of DNA within the nucleus. 4. **Structure of Nucleosome**: Each nucleosome consists of a histone octamer, which is made up of eight histone proteins, and about 146 base pairs of DNA that wrap around this histone core. 5. **Conclusion**: Based on the components of a nucleosome, the correct answer to the question "Nucleosome contains" is histones. ### Final Answer: Nucleosome contains histones. ---
