Select incorrect statement for DNA in bacteria :

Options

A. The length of the DNA strand may be about `2500-7000` times the length of the cell.
B. It is efficienty packed in the cell to fit within the nucleoid region.
C. The DNA is extensively looped and coiled with the help of nucleoid proteins.
D. Bacterial DNA is attached to cell membrane and the membrane may be involved in separation of dulicated DNA

Answer

To solve the question "Select incorrect statement for DNA in bacteria," we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding the Question**: We need to identify which statement about DNA in bacteria is incorrect.

2. **Evaluating the First Option**:
- The statement claims that the length of the DNA strand may be about 2,500 to 7,000 times the length of the cell.
- This statement is incorrect. In reality, bacterial DNA is approximately 23 times longer than the bacterial cell itself.

3. **Evaluating the Second Option**:
- The statement mentions that DNA is efficiently packed in the cell to fit within the nucleoid region.
- This statement is correct. The nucleoid region is where the bacterial DNA is located, and it is indeed packed efficiently.

4. **Evaluating the Third Option**:
- The statement states that the DNA is extensively looped and coiled with the help of nucleoid-associated proteins (NAP).
- This statement is also correct. NAPs help in organizing the DNA into a compact structure, allowing it to fit within the cell.

5. **Evaluating the Fourth Option**:
- The statement claims that bacterial DNA is attached to the cell membrane and that the membrane may be involved in the separation of duplicated DNA.
- This statement is correct as well. The attachment of DNA to the membrane plays a role in the segregation of DNA during cell division.

6. **Conclusion**: After evaluating all the options, the first option is the only incorrect statement regarding DNA in bacteria.

### Final Answer:
The incorrect statement for DNA in bacteria is: "The length of the DNA strand may be about 2,500 to 7,000 times the length of the cell."
