Which of the following is false?

Options

A. Most plant viruses are RNA viruses
B. Most animal viruses are DNA viruses
C. TMV has a doubled stranded RNA
D. `T_(4)` bacteriophage has doule stranded DNA molecule.

Answer

To determine which statement is false among the given options, we need to analyze each one carefully:

1. **Most plant viruses are RNA viruses.**
- This statement is true. The majority of viruses that infect plants are indeed RNA viruses.

2. **Most animal viruses are DNA viruses.**
- This statement is also true. While there are many RNA viruses that infect animals, a significant number of animal viruses are DNA viruses.

3. **TMV (Tobacco Mosaic Virus) has a double-stranded RNA.**
- This statement is false. TMV is known to be a single-stranded RNA virus, not double-stranded RNA.

4. **T4 bacteriophage is a double-stranded DNA molecule.**
- This statement is true. T4 bacteriophage is a well-known virus that has double-stranded DNA.

Based on the analysis, the false statement is: **TMV has a double-stranded RNA.**

### Step-by-step Solution:
1. Identify the statements given in the question.
2. Analyze each statement for its truthfulness based on known facts about viruses.
3. Confirm that TMV is a single-stranded RNA virus.
4. Conclude that the statement regarding TMV having double-stranded RNA is false.
