The correct Answer is:
To determine which prokaryote has linear DNA, we can analyze the options provided: 1. **Understanding Prokaryotes**: Prokaryotes are generally characterized by having circular DNA. However, there are exceptions where some prokaryotes may possess linear DNA. 2. **Analyzing the Options**: - **Chlamydia**: This is a genus of bacteria that is known to have circular DNA. Therefore, it does not fit the criteria of having linear DNA. **(Incorrect option)** - **Mycoplasma**: Mycoplasma is a genus of bacteria that lacks a cell wall and can exist in various shapes. Notably, Mycoplasma has linear DNA, which is an exception among prokaryotes. **(Correct option)** - **Bacterium**: Most bacteria have circular DNA. While there are rare exceptions, the majority of bacteria, including common genera, possess circular DNA. **(Incorrect option)** - **Cyanobacteria**: Similar to most bacteria, cyanobacteria typically have circular DNA. Thus, this option is also incorrect. **(Incorrect option)** 3. **Conclusion**: Based on the analysis, the prokaryote with linear DNA is **Mycoplasma**. ### Final Answer: The prokaryote with linear DNA is **Mycoplasma**. ---
