Gene battery model was proposed by

Options

A. Jacob and Monad
B. Gamow
C. H.G. Khorana
D. Britten and Davidson

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the scientist who proposed the gene battery model.

2. **Identifying the Options**: The options provided are:
- Option 1: Jacob and Monod
- Option 2: Gamma
- Option 3: H.G. Khurana
- Option 4: Britain and Davidson

3. **Background Knowledge**: The gene battery model is a concept related to the regulation of protein synthesis in eukaryotes. It was proposed in 1969 and elaborated in 1973.

4. **Analyzing Each Option**:
- **Option 1: Jacob and Monod**: They are known for their work on the lac operon, not the gene battery model. Thus, this option is incorrect.
- **Option 2: Gamma**: This scientist proposed a theory regarding the coding of amino acids, which does not relate to the gene battery model. Therefore, this option is also incorrect.
- **Option 3: H.G. Khurana**: He contributed to the chemical synthesis of RNA molecules but is not associated with the gene battery model. This option is incorrect as well.
- **Option 4: Britain and Davidson**: They proposed the gene battery model in 1969 and elaborated it in 1973. This is the correct option.

5. **Conclusion**: Based on the analysis, the correct answer is **Option 4: Britain and Davidson**.
