Flavr Savr is an example of recombinant DNA technology being used the supprose the native genes of an organism. Which of the following statements is not true w.r.t. flavr Savr ?

Options

A. It is a transgenic tomato variety
B. It has a relatively longer shelf life
C. Polygalacturnase enzyme synthesis is suppressed
D. Some toxins are produced in the plant, hence is not fit human consumption

Answer

To determine which statement is not true regarding Flavr Savr, we need to analyze each option in relation to what we know about this genetically modified tomato variety.

### Step-by-Step Solution:

1. **Understanding Flavr Savr**:
- Flavr Savr is a genetically modified tomato that was developed using recombinant DNA technology. It was designed to have a longer shelf life by suppressing the gene responsible for fruit softening.

2. **Analyzing the Options**:
- **Option A: It is a transgenic tomato variety**:
- This statement is true. Flavr Savr is indeed a transgenic variety because it contains genes that have been artificially introduced to modify its characteristics.

- **Option B: It has a relatively longer shelf life**:
- This statement is also true. The modification in Flavr Savr allows it to resist rotting, thus extending its shelf life compared to non-modified tomatoes.

- **Option C: Polygalacturonase enzyme synthesis is suppressed**:
- This statement is true as well. The introduction of an antisense gene in Flavr Savr suppresses the production of polygalacturonase, the enzyme responsible for breaking down pectin in the cell walls, which leads to fruit softening.

- **Option D: Some toxins are produced in the plant hence is not fit for human consumption**:
- This statement is not true. Flavr Savr tomatoes were deemed safe for human consumption and do not produce harmful toxins.

3. **Conclusion**:
- The statement that is not true regarding Flavr Savr is **Option D: Some toxins are produced in the plant hence is not fit for human consumption**.

### Final Answer:
The statement that is not true with respect to Flavr Savr is: **Some toxins are produced in the plant hence is not fit for human consumption.**
