Chromatin found in nucleus was discovered by

Options

A. Flemming
B. Schleiden
C. Schwann
D. Robert Brown

Answer

**Step-by-Step Solution:**

1. **Understanding Chromatin**: Chromatin is a complex of DNA and proteins found in the nucleus of eukaryotic cells. It plays a crucial role in packaging DNA into a smaller volume to fit in the nucleus and protect the DNA structure and sequence.

2. **Identifying the Scientists**: The question asks who discovered chromatin in the nucleus. The options provided are:
- A. Fleming
- B. Slyden
- C. Swan
- D. Robert Brown

3. **Analyzing Each Option**:
- **Option A: Fleming**: He is credited with the discovery of chromatin in the nucleus.
- **Option B: Slyden**: He, along with Schwann, contributed to the cell theory but did not discover chromatin.
- **Option C: Swan**: Like Slyden, he contributed to the cell theory but is not associated with the discovery of chromatin.
- **Option D: Robert Brown**: He discovered the nucleus itself but not chromatin.

4. **Conclusion**: Based on the analysis, the correct answer is **Option A: Fleming**, as he discovered that chromatin is found in the nucleus of the cell.

**Final Answer**: The chromatin found in the nucleus was discovered by **Fleming**.
