in bacteria plasmid is

Options

A. extra-chromosomal material
B. main DNA
C. non-functional DNA
D. repetitive gene

Explanation

To answer the question "In bacteria, plasmid is:", we will analyze the provided options and determine which one correctly describes plasmids.

### Step-by-Step Solution:

1. **Understanding Plasmids**:
- Plasmids are small, circular, double-stranded DNA molecules found in bacteria. They are distinct from the bacterial chromosome and can replicate independently.

2. **Analyzing the Options**:
- **Option A: Extractable material**: This suggests that plasmids can be isolated from the bacterial cell, which is true since they can be extracted for various purposes, including genetic engineering.
- **Option B: Main DNA**: This is incorrect because the main DNA in bacteria refers to the chromosomal DNA, not the plasmid.
- **Option C: Non-functional DNA**: This is misleading as plasmids often carry functional genes, such as those providing antibiotic resistance.
- **Option D: Repetitive gene**: This is not accurate as plasmids do not consist solely of repetitive sequences; they carry specific genes.

3. **Conclusion**:
- Based on the analysis, the correct answer is **Option A: Extractable material**. Plasmids can be extracted from bacteria and are important for various functions, including the transfer of genetic traits.

### Final Answer:
In bacteria, plasmid is **extractable material**.
