First artificial gene synthesized by khurana was a gene of

Options

A. Arginine
B. Lysine
C. Alanine t-RNA of yeast
D. Valine t-RNA

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the first artificial gene synthesized by Khurana. We need to identify which gene it was among the given options.

2. **Identifying the Options**: The options provided are:
- A) Arginine
- B) Lysine
- C) Alanine tRNA of yeast
- D) Valine tRNA

3. **Recalling Key Information**: The first artificial gene synthesized by Khurana is known to be related to tRNA, specifically from yeast.

4. **Analyzing Each Option**:
- Option A (Arginine) is incorrect.
- Option B (Lysine) is also incorrect.
- Option C (Alanine tRNA of yeast) is a known fact; Khurana synthesized this gene.
- Option D (Valine tRNA) is incorrect.

5. **Confirming the Correct Answer**: The correct answer is option C, which is the Alanine tRNA of yeast. This gene consists of 126 nucleotides and plays a crucial role in RNA synthesis.

6. **Conclusion**: The first artificial gene synthesized by Khurana was the Alanine tRNA gene from yeast.
