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 regarding viruses, we will analyze each option step by step.

### Step 1: Analyze Option 1
**Statement:** Most plant viruses are RNA viruses.
**Analysis:** This statement is true. Most plant viruses, including the Tobacco Mosaic Virus (TMV), are indeed RNA viruses.

### Step 2: Analyze Option 2
**Statement:** Most animal viruses are DNA viruses.
**Analysis:** This statement is also true. While there are RNA viruses that infect animals, many of the well-known animal viruses, such as the Herpesvirus, are DNA viruses.

### Step 3: Analyze Option 3
**Statement:** TMV has a double-stranded RNA.
**Analysis:** This statement is false. The Tobacco Mosaic Virus (TMV) contains single-stranded RNA (ssRNA), not double-stranded RNA. Therefore, this statement is incorrect.

### Step 4: Analyze Option 4
**Statement:** T4 bacterial phage has a double-stranded DNA molecule.
**Analysis:** This statement is true. The T4 bacteriophage, which infects bacteria, does indeed have a double-stranded DNA (dsDNA) genome.

### Conclusion
After analyzing all the options, we find that **Option 3** is the false statement.

### Final Answer:
**Option 3 is false.**
