Genetically engineered bovine (rbST), sometimes called rbT (recombinant bovine samototropin) or rbGH (recombinant brovine growth hormone) are used in the

Options

A. Therapeutic drugs
B. Agriculture
C. Dairy industry
D. DNA fingerprinting

Answer

**Step-by-Step Solution:**

1. **Understanding rbST**: Recognize that rbST (recombinant bovine somatotropin) is a genetically engineered hormone used in cattle. It is also referred to as rbGH (recombinant bovine growth hormone).

2. **Function of rbST**: Understand that rbST is a growth hormone that plays a crucial role in regulating growth and milk production in dairy cows. It enhances milk yield by increasing the efficiency of feed conversion into milk.

3. **Analyzing the Options**: Look at the provided options:
- Therapeutic drugs
- Agriculture
- Dairy industry
- DNA fingerprinting

4. **Evaluating Each Option**:
- **Therapeutic drugs**: While rbST is a hormone, it is not primarily classified as a therapeutic drug for human use.
- **Agriculture**: Although it is used in agricultural practices, it is not directly related to crop production.
- **Dairy industry**: rbST is primarily used in the dairy industry to increase milk production in cows.
- **DNA fingerprinting**: This option is unrelated to the function of rbST.

5. **Selecting the Correct Answer**: Based on the analysis, the most appropriate use of rbST is in the **dairy industry**, as it is specifically designed to enhance milk production in cows.

**Final Answer**: The correct answer is the **dairy industry**.
