In case of Bam HI , H represents

Options

A. Genus
B. Species
C. Name of scientist
D. Strain

Answer

To answer the question "In case of Bam HI, H represents," we need to analyze the naming convention of restriction endonucleases, specifically Bam HI.

### Step-by-Step Solution:

1. **Understanding Bam HI**:
- Bam HI is a type of restriction endonuclease, which is an enzyme that cuts DNA at specific sequences.

2. **Naming Convention**:
- The naming of restriction enzymes follows a specific convention:
- The first letter represents the **genus** of the bacterium from which the enzyme is derived.
- The second and third letters represent the **species** of that bacterium.
- The fourth letter represents the **strain** of the species.
- The Roman numeral indicates the order of discovery of that enzyme.

3. **Identifying Components of Bam HI**:
- In the case of Bam HI:
- "B" stands for the genus **Bacillus**.
- "a" and "m" stand for the species **amyloliquefaciens**.
- "H" represents the **strain** of the species.
- "I" indicates that it was the first enzyme discovered from that strain.

4. **Conclusion**:
- Therefore, in Bam HI, the letter "H" specifically represents the **strain** of the species.

### Final Answer:
- H represents the **strain**.
