Chromatin/chromosome consitsts of

Options

A. DNA
B. RNA
C. RNA and histones
D. DNA and histones

Answer

To answer the question "Chromatin/chromosome consists of", we can break down the components of chromatin and chromosomes step by step.

### Step-by-Step Solution:

1. **Understanding Chromatin and Chromosomes**:
- Chromatin is a complex of DNA and proteins found in the nucleus of eukaryotic cells. When the cell is not dividing, chromatin is in a relaxed state.
- Chromosomes are the condensed form of chromatin that occurs during cell division.

2. **Components of Chromatin/Chromosomes**:
- Chromatin consists primarily of DNA and proteins. The two main types of proteins associated with chromatin are histones and non-histone proteins.

3. **Role of Histones**:
- Histones are basic proteins that help in the packaging of DNA. They have a high content of basic amino acids, which allows them to bind tightly to the negatively charged DNA.

4. **Structure of Chromatin**:
- In chromatin, DNA is wrapped around a core of eight histone proteins, forming a structure known as a nucleosome. This organization allows for efficient packing of DNA within the nucleus.

5. **Other Proteins**:
- In addition to histones, chromatin also contains non-histone proteins, which play various roles in gene regulation and chromatin structure.

6. **Conclusion**:
- Therefore, the correct answer to the question is that chromatin/chromosomes consist of **DNA and histones**.

### Final Answer:
Chromatin/chromosomes consist of **DNA and histones**.
