Identify the name of single bacterial chromosome.

Options

A. DNA
B. RNA
C. Ribosome
D. Nucleoid

Answer

**Step-by-Step Solution:**

1. **Understanding Bacterial Structure**: Bacteria are prokaryotic organisms, which means they lack a defined nucleus and other membrane-bound organelles.

2. **Identifying Chromosome in Bacteria**: In bacteria, the genetic material is not enclosed within a nuclear membrane. Instead, it is found in a region of the cell called the nucleoid.

3. **Defining the Nucleoid**: The nucleoid is the area where the single bacterial chromosome is located. It is directly in contact with the cytoplasm since there is no nuclear membrane separating it.

4. **Characteristics of Bacterial Chromosome**: The bacterial chromosome is typically circular and double-stranded. It is also associated with non-histone proteins, which help in organizing the DNA.

5. **Conclusion**: Therefore, the name of the single bacterial chromosome is referred to as the nucleoid.

6. **Final Answer**: The correct answer is option D: Nucleoid.
