Which of the following statements is false ?

Options

A. TMV has double-stranded RNA molecule
B. Most plant viruses are RNA viruses
C. The bacteriophage has a double -stranded DNA molecule
D. Most animal virsues are DNA viruses

Answer

To determine which statement is false, we will analyze each option provided in the question.

### Step 1: Analyze Option 1
- **Statement**: TMV has the double-stranded RNA molecule.
- **Analysis**: TMV stands for Tobacco Mosaic Virus, which is known to have a single-stranded RNA (ssRNA) genome, not double-stranded RNA (dsRNA).
- **Conclusion**: This statement is false.

### Step 2: Analyze Option 2
- **Statement**: Most plant viruses are RNA viruses.
- **Analysis**: This statement is true. A significant number of plant viruses are indeed RNA viruses.
- **Conclusion**: This statement is true.

### Step 3: Analyze Option 3
- **Statement**: The bacteriophage has the double-stranded DNA molecule.
- **Analysis**: Bacteriophages, which are viruses that infect bacteria, typically contain double-stranded DNA (dsDNA).
- **Conclusion**: This statement is true.

### Step 4: Analyze Option 4
- **Statement**: Most animal viruses are DNA viruses.
- **Analysis**: This statement is somewhat misleading. While there are many DNA viruses that infect animals, a significant number of animal viruses are RNA viruses. Therefore, it is not accurate to say that most animal viruses are DNA viruses.
- **Conclusion**: This statement is misleading and can be considered false depending on interpretation.

### Final Conclusion
- The false statement among the options is **Option 1**: TMV has the double-stranded RNA molecule.
