Prokaryotic DNA is `:`

Options

A. double stranded round
B. single stranded round
C. double stranded straight
D. double stranded RNA as nucleic acid

Answer

To answer the question "Prokaryotic DNA is:", we need to analyze the characteristics of DNA in prokaryotic organisms.

### Step-by-Step Solution:

1. **Understanding Prokaryotic Cells**: Prokaryotic cells are unicellular organisms that lack a defined nucleus and membrane-bound organelles. This includes bacteria and archaea.

2. **Location of DNA**: In prokaryotes, the genetic material (DNA) is not enclosed within a nucleus. Instead, it is found in a region of the cytoplasm called the nucleoid.

3. **Structure of Prokaryotic DNA**: The DNA in prokaryotic cells is typically circular in shape. Unlike eukaryotic DNA, which is linear and associated with histone proteins, prokaryotic DNA is not associated with histones in the same way.

4. **Strandedness of Prokaryotic DNA**: Prokaryotic DNA is double-stranded, meaning it consists of two strands that form a double helix structure. This is similar to eukaryotic DNA, which is also double-stranded.

5. **Conclusion**: Based on the characteristics outlined above, we conclude that prokaryotic DNA is double-stranded and circular (round).

### Final Answer:
Prokaryotic DNA is double-stranded and round.
