Procaryotic genetic material is

Options

A. Linear DNA+ histones
B. Circular DNA +histones
C. Linear DNA without histones
D. Circular DNA without histones.

Answer

**Step-by-Step Solution:**

1. **Understanding Prokaryotic Cells:**
- Prokaryotic cells are unicellular organisms, which means they consist of a single cell. They are among the earliest forms of life on Earth and include bacteria and archaea.

2. **Characteristics of Prokaryotic Cells:**
- Prokaryotic cells have a simple structure, typically consisting of a single membrane surrounding the cytoplasm where all cellular reactions occur.

3. **Genetic Material in Prokaryotes:**
- The genetic material in prokaryotic cells is not organized into a nucleus like in eukaryotic cells. Instead, it is found in a region called the nucleoid, which is disorganized.

4. **Form of DNA:**
- The DNA in prokaryotes is circular in shape, which is a key characteristic that distinguishes it from the linear DNA found in eukaryotic cells.

5. **Histones Presence:**
- Unlike eukaryotic DNA, which is associated with proteins called histones, prokaryotic DNA is devoid of histones. This means that prokaryotic DNA does not have these proteins associated with it.

6. **Evaluating the Options:**
- Given the options:
- Option A: Linear DNA plus histones (Incorrect)
- Option B: Circular DNA plus histones (Incorrect)
- Option C: Linear DNA without histones (Incorrect)
- Option D: Circular DNA without histones (Correct)
- The correct answer is option D, as prokaryotic genetic material is circular DNA without histones.

7. **Conclusion:**
- Therefore, the correct answer to the question "Prokaryotic genetic material is" is **circular DNA without histones**.
