Genes were first artificially synthesized by `:`

Options

A. Galton
B. Watson
C. Mendel
D. Khorana

Answer

To answer the question "Genes were first artificially synthesized by:", we will analyze the options provided and identify the correct scientist.

### Step-by-Step Solution:

1. **Identify the Options**: The question provides several options, including notable scientists in genetics and molecular biology.

2. **Evaluate Each Scientist**:
- **Carlton**: The transcript mentions Carlton in relation to human selective breeding. However, he did not synthesize genes. Therefore, he is not the correct answer.
- **Watson and Crick**: Known for discovering the double helix structure of DNA, they contributed significantly to molecular biology but did not synthesize genes artificially. Hence, they are not the correct answer.
- **Mendel**: Recognized as the father of genetics, Mendel formulated the laws of inheritance but did not engage in gene synthesis. Thus, he is also not the answer.
- **Hargobind Khurana**: The transcript states that Hargobind Khurana was involved in artificial gene synthesis, also referred to as DNA printing. This indicates that he is the correct answer.

3. **Conclusion**: After evaluating all the options, the correct answer to the question is Hargobind Khurana, as he was the first to artificially synthesize a gene.

### Final Answer:
Genes were first artificially synthesized by **Hargobind Khurana**.
