Which of the following is a DNA containing plant virus

Options

A. TMV
B. Cauliflower Mosaic Virus
C. Potato Mosaic Virus
D. Both B and C.

Answer

To determine which of the following is a DNA containing plant virus, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Viruses**:
- Viruses can be classified based on their genetic material into two main categories: DNA viruses (deoxyviruses) and RNA viruses (riboviruses).

2. **Identify Plant Viruses**:
- Plant viruses are specifically referred to as phytoviruses. It is important to know examples of these viruses to identify which of them contain DNA.

3. **Evaluate the Options**:
- The question presents several options. We need to analyze each option to determine whether it is a DNA virus or an RNA virus.

4. **Analyze Each Option**:
- **Option 1: Tobacco Mosaic Virus (TMV)**: This virus is known to cause mosaic disease in tobacco plants. It is actually an RNA virus, not a DNA virus.
- **Option 2: Cauliflower Mosaic Virus**: This virus affects cauliflower and is also known to be an RNA virus.
- **Option 3: Potato Mosaic Virus**: This virus affects potatoes and is known to be a single-stranded RNA virus.

5. **Correct Identification**:
- It appears that none of the options listed are DNA viruses. However, if we consider the context of the question and the common knowledge about plant viruses, the correct answer should be a known DNA virus, such as the **Cauliflower Mosaic Virus**, which is indeed a DNA virus.

6. **Conclusion**:
- Based on the analysis, the answer to the question is that the **Cauliflower Mosaic Virus** is a DNA containing plant virus.
