Temin worked on virus

Options

A. Rhinovirus
B. Dengue Virus
C. Herpes virus
D. Retrovirus

Answer

**Step-by-Step Solution:**

1. **Identify the Scientist and His Work**: The question mentions "Temin," which refers to Howard Temin, who is known for his research on retroviruses.

2. **Understand Retroviruses**: Retroviruses are a type of virus that have RNA as their genetic material. They are unique because they can convert their RNA into DNA using an enzyme called reverse transcriptase.

3. **Recognize the Process**: The process that retroviruses undergo is known as reverse transcription. In this process, the viral RNA is converted into complementary DNA (cDNA), which can then integrate into the host's genome.

4. **Differentiate Between Virus Types**: The question provides four options: Rhinovirus, Dengue virus, Herpes virus, and Retrovirus.
- Rhinovirus: Causes the common cold and is an RNA virus but not a retrovirus.
- Dengue virus: Also an RNA virus but not a retrovirus.
- Herpes virus: A DNA virus, not a retrovirus.
- Retrovirus: This is the correct answer as it is the type of virus Temin worked on.

5. **Conclusion**: Based on Temin's work with retroviruses and the unique characteristics of these viruses, the correct answer to the question is **Retrovirus**.

**Final Answer**: The correct option is **Retrovirus** (option D).
