Folded Fibre Model of chromatin was proposed by

Options

A. Dupraw
B. Kornberg
C. Thomas
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the proposal of the folded fibre model of chromatin. We need to identify the scientist responsible for this model.

2. **Analyzing the Options**: The options provided are:
- A) Dupro
- B) Conberg
- C) Thomas
- D) All of the above

3. **Evaluating Each Option**:
- **Option A (Dupro)**: Dupro is known for proposing the folded fibre model of chromatin in 1965. This option seems promising.
- **Option B (Conberg)**: Conberg is recognized for discovering the DNA polymerase enzyme, not for the folded fibre model. Thus, this option is incorrect.
- **Option C (Thomas)**: Thomas is known for establishing the chromosome theory of heredity, which does not relate to the folded fibre model. Therefore, this option is also incorrect.
- **Option D (All of the above)**: Since both Conberg and Thomas are not associated with the folded fibre model, this option cannot be correct.

4. **Conclusion**: Based on the analysis, the only correct answer is **Option A (Dupro)**, as he proposed the folded fibre model of chromatin.

**Final Answer**: The folded fibre model of chromatin was proposed by Dupro.
