Which of these cannot be related to biotechonlogy ?

Options

A. Integration of natural science and organisms.
B. Techniques to alter the chemistry of DNA.
C. Introduction of undesirable genes into the target organisms
D. Maintenance of sterile ambience to enable the growth of only the desired microbes.

Answer

To solve the question "Which of these cannot be related to biotechnology?", we will analyze each option provided in the question and determine their relevance to biotechnology.

### Step-by-Step Solution:

1. **Understanding Biotechnology**:
Biotechnology involves the use of living organisms or their components to develop products and technologies. It often includes genetic manipulation, cloning, and the maintenance of sterile conditions for growth.

2. **Analyzing Option 1**:
- **Integration of the natural science of organisms**: This is related to biotechnology as it involves understanding the biology of organisms to manipulate them for desired outcomes.
- **Conclusion**: This option is related to biotechnology.

3. **Analyzing Option 2**:
- **Techniques to alter the chemistry**: This refers to changing the biochemical pathways in organisms, which is a fundamental aspect of biotechnology (e.g., genetic engineering).
- **Conclusion**: This option is related to biotechnology.

4. **Analyzing Option 3**:
- **Introduction of undesirable genes into the target organism**: This is not a typical goal of biotechnology. Biotechnology aims to introduce desirable traits, not undesirable ones. Introducing undesirable genes would be counterproductive.
- **Conclusion**: This option is NOT related to biotechnology.

5. **Analyzing Option 4**:
- **Maintenance of sterile ambience to enable the growth of only a desired microbe**: This is a standard practice in biotechnology to prevent contamination and ensure that only the desired organism grows.
- **Conclusion**: This option is related to biotechnology.

### Final Answer:
The option that cannot be related to biotechnology is **Option 3: Introduction of undesirable genes into the target organism**.
