The gene enconding brazzein was patented in _______ and was proposed to transfer into ____

Options

A. USA, maize
B. USA, sugarcame
C. Germany , pentadiplandra
D. Germany, maize

Answer

**Step-by-Step Solution:**

1. **Identify the Gene and Its Properties:**
- The gene encoding brazzein is known for producing a protein that is significantly sweeter than sugar, approximately 2,000 times sweeter.

2. **Determine the Patent Information:**
- The gene encoding brazzein was patented in the United States. This information is crucial as it indicates the legal ownership and rights associated with the gene.

3. **Identify the Proposed Host for Gene Transfer:**
- The proposed organism for the transfer of the brazzein gene is maize (corn). This is significant as it indicates the intended application of biotechnology in agriculture.

4. **Understand the Purpose of Gene Transfer:**
- The goal of transferring the brazzein gene into maize is to express the gene in maize kernels, allowing for the extraction of the sweet protein for use as a low-calorie sweetener.

5. **Summarize the Findings:**
- Therefore, the complete answer to the question is: "The gene encoding brazzein was patented in the USA and was proposed to transfer into maize."

**Final Answer:**
The gene encoding brazzein was patented in **USA** and was proposed to transfer into **maize**.
