In QB Bacteriophase genetic material is

Options

A. DNA
B. RNA
C. Protein
D. None

Answer

**Step-by-Step Solution:**

1. **Understanding Bacteriophages**: Bacteriophages, or phages, are viruses that specifically infect bacteria. They consist of genetic material surrounded by a protein coat.

2. **Identifying the Type of Genetic Material**: In general, the genetic material of bacteriophages is predominantly DNA. However, there are exceptions where RNA can serve as genetic material.

3. **Focusing on QB Bacteriophage**: The question specifically asks about the QB bacteriophage, also known as cubi bacteriophage.

4. **Researching the QB Bacteriophage**: Upon researching the QB bacteriophage, we find that it is indeed unique compared to many other bacteriophages.

5. **Determining the Genetic Material**: The genetic material of the QB bacteriophage is positive strand RNA. This is a key distinction since most bacteriophages typically have DNA as their genetic material.

6. **Conclusion**: Therefore, the genetic material in QB bacteriophage is RNA.

**Final Answer**: The genetic material in QB bacteriophage is RNA.
