Within nucleus, DNA is organised along with proteins into material called

Options

A. Nuclear lamina
B. Chromosome
C. Chromatid
D. Chromatin

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the organization of DNA within the nucleus along with proteins.

2. **Identifying the Options**: The options provided are:
- Nuclear lamina
- Chromosome
- Chromatin
- Chromatic

3. **Analyzing the Options**:
- **Nuclear lamina**: This is a network of protein filaments that provides structural support to the nucleus but does not refer to the organization of DNA.
- **Chromosome**: This is a structure that contains DNA and proteins, but it is typically formed during cell division and is not the term used for the organization of DNA in its relaxed state.
- **Chromatin**: This is the correct term for the material within the nucleus where DNA is organized along with proteins.
- **Chromatic**: This term does not relate to the organization of DNA in the nucleus.

4. **Choosing the Correct Answer**: Based on the analysis, the correct answer is **chromatin**.

5. **Defining Chromatin**: Chromatin is a viscous gelatinous substance made up of DNA and proteins. It consists of:
- **Histone proteins**: Basic proteins that help in packaging DNA.
- **Non-histone proteins**: Acidic proteins that also play a role in the structure and function of chromatin.

6. **Understanding the Etymology**: The term "chromatin" is derived from the Greek word "chroma," meaning color, and the suffix "-in," which is used in chemistry to denote a substance.

7. **Final Answer**: Therefore, within the nucleus, DNA is organized along with proteins into a material called **chromatin**.
