Which one is a correct statement

Options

A. "Bt" in "Bt Cotton" indicates that it is a genetically modified organism produced through biotechnology
B. Classical plant breeding involves fusion of two somatic cells carrying desired gnes
C. Anticoagulant hirudin is being produced from seeds of transgenic Brassica napus
D. Golden Rice is a transgenic variety of rice rich in vitamin E

Answer

To determine which statement is correct, let's analyze each option step by step:

1. **Option A: BT in BT cotton indicates that it is a genetically modified organism produced through biotechnology.**
- **Analysis:** The term "BT" stands for Bacillus thuringiensis, which is a bacterium used in the genetic modification of cotton to make it resistant to certain pests. Therefore, saying that BT indicates it is a genetically modified organism produced through biotechnology is misleading. The "BT" specifically refers to the bacterium, not the process of biotechnology itself.
- **Conclusion:** This statement is **incorrect**.

2. **Option B: Classical plant breeding involves fusion of two somatic cells carrying desired genes.**
- **Analysis:** Classical plant breeding primarily involves the hybridization of pure lines and subsequent artificial selection. The fusion of two somatic cells is a different technique known as somatic hybridization, which is not part of classical plant breeding.
- **Conclusion:** This statement is **incorrect**.

3. **Option C: Anticoagulant hirudin is being produced from seeds of transgenic Brassica napus.**
- **Analysis:** Hirudin is indeed an anticoagulant that has been produced using transgenic plants, including Brassica napus (canola). This statement accurately reflects a current application of biotechnology.
- **Conclusion:** This statement is **correct**.

4. **Option D: Golden rice is a transgenic variety of rice rich in vitamin E.**
- **Analysis:** Golden rice is genetically modified to produce beta-carotene, which is a precursor to vitamin A, not vitamin E. Therefore, this statement is incorrect.
- **Conclusion:** This statement is **incorrect**.

**Final Answer:** The correct statement is **Option C: Anticoagulant hirudin is being produced from seeds of transgenic Brassica napus.**
