Genetic material of reovirus is

Options

A. DNA
B. RNA
C. DNA and RNA
D. Nucleoprotein complexes.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:** The question asks for the genetic material of reovirus. We need to identify what type of genetic material is present in this virus.

2. **Reviewing the Options:** The options provided are:
- A) DNA
- B) RNA
- C) DNA and RNA
- D) Nucleoprotein complexes

3. **Defining Genetic Material:** Genetic material is the substance that carries genetic information in an organism. It can be DNA (deoxyribonucleic acid) or RNA (ribonucleic acid).

4. **Characteristics of Reovirus:** Reoviruses are known to be non-enveloped viruses with an icosahedral capsid structure. They are characterized by their unique genetic material.

5. **Identifying the Genetic Material of Reovirus:** Reoviruses specifically contain double-stranded RNA (dsRNA) as their genetic material. This distinguishes them from other types of viruses that may contain DNA or single-stranded RNA.

6. **Evaluating the Options Against the Information:**
- Option A (DNA) is incorrect because reoviruses do not contain DNA.
- Option B (RNA) is partially correct, but it does not specify that it is double-stranded RNA.
- Option C (DNA and RNA) is incorrect as reoviruses do not contain both.
- Option D (Nucleoprotein complexes) is also incorrect.

7. **Conclusion:** The correct answer is that the genetic material of reovirus is double-stranded RNA. Therefore, the best choice from the options provided is **Option B (RNA)**, as it represents the type of genetic material, albeit without specifying that it is double-stranded.

**Final Answer:** The genetic material of reovirus is double-stranded RNA (dsRNA).
