Genetic material of retroviruses is

Options

A. ss DNA
B. ss RNA
C. Protein
D. ds DNA

Answer

**Step-by-Step Solution:**

1. **Identify the Type of Virus**: The question asks about the genetic material of retroviruses. Retroviruses are a specific type of virus known for their unique replication process.

2. **Recall the Genetic Material of Retroviruses**: Retroviruses, such as HIV, are known to have RNA as their genetic material. Specifically, they contain single-stranded RNA (ssRNA).

3. **Understand the Replication Process**: When a retrovirus infects a host cell, it releases its RNA into the host. The virus then uses an enzyme called reverse transcriptase to convert its RNA into DNA.

4. **Clarify the Options**: The options given were single-stranded DNA, single-stranded RNA, protein, or double-stranded DNA. Based on our understanding of retroviruses, we can eliminate the other options:
- Single-stranded DNA: Incorrect, as retroviruses do not contain DNA as their genetic material.
- Protein: Incorrect, as proteins are not genetic material.
- Double-stranded DNA: Incorrect, as retroviruses do not have double-stranded DNA as their genetic material.

5. **Conclude the Answer**: The correct answer is single-stranded RNA, as it accurately describes the genetic material of retroviruses.

**Final Answer**: The genetic material of retroviruses is single-stranded RNA.
