Who among the following scientists is associated with the discoveries in genetic engineering

Options

A. Khorana
B. Watson
C. Crick
D. Meselson

Explanation

**Step-by-Step Solution:**

1. **Identify the Scientists**: The question asks which scientist is associated with discoveries in genetic engineering. The options provided are Khurana, Crick, Watson, and Misselson.

2. **Analyze Each Scientist's Contribution**:
- **Har Gobind Khurana**: He is known for synthesizing artificial genes in 1969, which is a significant contribution to genetic engineering.
- **James Watson and Francis Crick**: They are famous for proposing the double helix structure of DNA, which is fundamental to genetics but not specifically genetic engineering.
- **Matthew Meselson and Franklin Stahl**: They conducted experiments that demonstrated the semi-conservative nature of DNA replication, which is crucial in genetics but not directly linked to genetic engineering.

3. **Determine the Correct Answer**: Based on the contributions, Har Gobind Khurana is the scientist most closely associated with genetic engineering due to his work on artificial genes.

4. **Conclusion**: Therefore, the correct answer to the question is option A, Har Gobind Khurana.
